If you bolt SBC heads onto a 6.2 i want pictures :laughing:


That is like a chick wearing a cup

hahaha, a gasser with 17:1 compression!!! gonna have to retard that timing alot because its gonna start dieseling. lol

The distributor might give you alittle trouble but good luck let us know how that works for you. :laughing:

Go for it! I heard that combo would make for a kick-ass engine.

umm........... I dont think thats gonna work dude.

Whoa....

Um...

Yeah...

No, it won't work. Not even kinda.

You want to go to gas you need to change the motor.

Try sorting out your 6.2 issues, they are just about the simplest motor out there and should be easy to figure out and fix.

Well maybe nit for you....

well man, i know detroit diesel designed the 6.2 from the ground up. i dont think they are the same, also the pistons are wayyyyyy off to work in a gasser combustion chamber.

Hey, Hey, Hey guys whadda 'spect---it's TUESDAY!!!!

yea, but thats for the 350 diesel not the 6.2 detroit.

i didn't catch that it was a 5.7 intill after i posted it. i just remembered reading it. hopefully some of it helps him realize that its not worth the time or money.

exactly, why redesign an engine that 50+ engineers designed to work. i highly doubt you would make it better. also.... its a damn 6.2 diesel, just fix it and be happy with the good fuel milage you get and laugh at all the guys getting 6 mpg with thier 383 strokers.

I think you should put the SBC heads on a SBF as you'd get much better power and economy from them. Also, the compression ratio won't be as high as if you put the SBC heads on to the 6.2 diesel block. As for an intake manifold just use a SBC intake BUT besure to weld the dizzy hole in the rear and re-drill a new dizzy hole in the front for the Ford diz. Best of luck to you on this project. Sounds like an interesting one, keep us posted, and besure to post dyno results.

for your 6.2 problems go to dieselplace.com and get it sorted out, they are a simple engine and 9 out of 10 times its a fuel problem with them. so check the diesel first, and i'm not sure but would sbc heads fit anyways?

Are you shitting me????

ok first off you have no idea how an engine works, whether gas or diesel. diesel engines fire on compression, have no spark plugs, distributor or anything.

the 6.2L is NOT simply a 383 stroker w/ high compression, it is an entirely different engine, ENTIRELY. this is not a sbc variant like the olds diesel.

next time you have a question, think, research, or at least learn about your junk first.

this is why evolution is a good thing, people like this may someday be weeded out of the gene pool

Are you shitting me????

X 2:shaking:

I'm not a diesel person myself, but I don't think they have a distributor.

That might be a problem right there.:laughing:

Come on guys. Don't discourage the lad. I think he's on to something here.


For Petes sake. another poor soul that thinks that Wyotech is going to make him an expert.

You might try reading about things on your own. I grew up on Hot Rod and Truckin mags, and then damn near everything in the peterson lineup before they became the sorry rags they are today. And I still read everything that even remotely interests me, because there is always the chance I might take something from it and be able to use it. I've read damn near every buildup on Pirate, copied a lot of ideas I liked, ruled out the ones I didn't, not because they were bad, but they weren't what I wanted.

There is nothing wrong with wanting to push the envelope a bit, we all do. But you have to have some baseline of knowledge to start with.


My first impulse was to let you have it with both barrels, and I ain't quite over it yet, but you caught me in a good mood. It's not quite as stupid as some I've read in the last few days, but you didn't do your homework, You just pulled something out of your ass, didn't even look at it to see if it was possible, and then came on here wanting everyone to pat you on the head and tell you what a bright lad you are. Then, when told it wouldn't work, you still didn't go and look for yourself, you argued about it, even tho you were completely ignorant of the facts. That puts you right up there with a lot of assholes I know. Not the best company to be associated with.


Know what you are talking about BEFORE you open your mouth. It'll save you a lot of grief in these here parts.


Doug

I'll be the nice guy and simply say your information is a mish-mash of...well...misinformation.

I would have to think the Isuzu-GM association thing stems from the much newer Duramax motors which are in fact Isuzu sourced.

The idea that the intake and heads will swap over stems from the 350 Olds diesel thing and even then it most certainly is not a direct swap as I'm sure you will find with some reading.

Yep, the 6.2 is kind of in its own world. It is not in any way, shape, or form a small block Chevy. You really just need to decide to fix it or replace it entirely. You can't just re-engineer it in your backyard. It just doesn't work that way. Thinking outside the box is good, but you need to keep sight of the box when you're doing it.:D

Hey, I thought I was being nice.

Bye.

:shaking:

I'll be an asshole and say that this guy doesn't know jack shit about much, regarding engines.

But hell yeah, try it. But for fuck's sake, dont' know a damn thing about 6.2 and SBC architecture. Oh, don't do that, because if you did, you'd have shut your own stupid mouth before you got started.

This might just be the dumbest thing I've ever read. :rolleyes:

The 6.2 doesn't connotate a 383 either. it's a 379 ci diesel engine built by detroit diesel which was the precursor of the more current 6.5 (pre D-max).
The 5.7 Oldsmobile diesel was a converted gas engine and it was prone to cracking the block. Diesels have twice the compression of a gas engine to ignite the diesel fuel with no spark. they don't even have conventional throttle bodies.

And to switch you diesel to a gas engine, even for the olds, would relate to alot of work anyway and alot of parts and money. Get a new fuel pump and filter/seperator, some fuel treatment (to clean out gunk in the tank and lines) and some new glow plugs and a controller. those are the most common areas of the 6.2 to be replaced. If you can't find out bring it to a mechanic and have him describe what he had done. you gotta learn somewhere.

[double post.]

The 5.7 Oldsmobile diesel was a converted gas engine and it was prone to cracking the block.
Wrong. You can convert an Olds diesel to GAS, but it is a different block than a gas block. I have no idea where you get this block cracking shit either, considering the diesel block was beefed up. Head gaskets is what went all the time on the Olds diesel's.

working on it, not a expert yet...i am going to wyotech next month so i will be closer then.
lol.

lol just curious on everyones opinion on wyotech here? we own a bodyshop and i know that the techs coming out of the body program are kinda a joke to the industry...

Dude, I'm still think it could work. Might require some time with a cut-off wheel and grinder to make the heads and intake fit, but the parts are all free, right?? For the compression ratio issue all you need is a different set of 350 pistons, should drop right in since it's the same issue...just remember you will need pistons for a 350 with a 0.200 overbore....

bucksntrucks969-i know plenty on how a motor work...come back when your balls drop, idiot!

DUG-you shouldnt act like you know somone, or the situation

yozsi-i appriciate your sigestions and knowledge

supervert-that was a very informative thread, i searched for the 6.2 and found nothing didnt think to try the 350.

To the rest of you pesimistic FUCKER that call me stupid but you cannot even read:
The SBC heads have spark pulg ports
Intake had distrubutor hole
6.2L Diesels have vacum pump that are in the same spot as the distrubutar


Sorry my research was not completed, i took "hear say" from someone and took it to be correct and thought that this was closer to a posibility.

THINGS THAT I WILL ADMIT TO BEING WRONG ON!!!!:
I was under the understanding that the 6.2 was built by chevy and assembled by Isuzu, this was somthing that was told to me when i first bought the truck.
I did not take into account the fact that the piston determan the compression ratio.


I never said that i wanted to do this, if you were to read this whole thread at the begining you would see that i said "this is not my first choice". I am already working on getting the diesel running (with the help of thedieselpages.com....link to thread (http://www.thedieselpageforums.com/tdpforum/showthread.php?t=28591)) i just saw that i have an extra set of heads, intake, carb, distrubutar, figured i would see if it was even a posibility. it never hurts to ask, it is not like i am trying to build a V12 by combinding two slant 6 or something. it is just i was under the wrong impression. unlike some other people here i dont claim to know all, i am 22 with a good amount of knowledge (for my age) when it comes to vehicals, (spelling is another story as you can all tell by now). i dont appriciate people that just have to be mean when someone is just asking a question, i didnt say that this is what i am doing i just wanted to know if it was a posiblity, figured this is a good place to see if i was on the right page, but i am finding that yeah this is the biggest 4x4 web site...but if guys are going to be like that then to hell with this.

If you think you can slap a set of SBC heads on a 6.2 and make a gas motor then you do not have a good amount of knowledge for your age.

First off your whole logic behind a 6.2 being the same as a 383 doesn't work because the displacement does not even match.

A quick look at the respective timing covers, water pumps and intake/exhaust port/valve placement should have shown you that where dealing with very different motors. Same thing goes for the physical size of the motor.

x2, seriously...I'm beginning to think you have never seen either a 6.2 or any displacement SBC, ever.

Hey, I am young too (23) but at least I look at my junk if I am going to go spout off BS about it on the intarweb. :shaking:

Oh, and there is a newbie forum for a reason. If you want to get all defensive, either drop the hardass bullshit and read, read, read until your head hurts, or you will leave this site crying about how your bum goes ouch because of the meanies there.

You're about as retarded as Spunksucker, or whatever his name is.

DO NOT, I repeat, DO NOT actually look at the engines you're running your mouth about. Hell no! :shaking:

The diesel olds was beefed up but not sufficiently. It is a flawed motor and should only be used as basic transportation. with regular maintenance they can live a long life, but i have personally seen 2 cracked olds diesel blocks my self. And the olds diesel can be converted back to gas, it's just a waste of time. Why wouldn't one just go get a 350 gas block instead of putting on all the new components to convert one.

The bore spacing is not sufficient enough to beef up a gas motors cylinder walls enough to adequately handle the diesels compression inginition cycle for a long service life. It does not have the durability of a devoted diesel block. I'm not saying it's not doable it's just not the best. But thats a little OT and i am in no way trying to start a fight here. Peace.

If you did some research, the 6.2 diesels bore is 3.98" and the 350's is 4.00" you would not need an overbore you would need to bore out the diesels bore if it would work. Just swap in a 350 if you can get the parts for free if you think it would be easier. Than have fun with the harnesses and fuel lines, tank etc. it would be alot easier to fix the 6.2L. But a 350 swap is not out of the question. It is also 10 times easier than your planned project.

WOW! stupid tuesday thread spilled into wednesday with everyone getting butthurt. got popcorn going :p:p

it was a long weekend for the tards, they think its tuesday.

diesel + gas heads = i like turtles

fawkin retard...

re reading and trying to be of assistance, i have come to a conclusion your dead set on trying to put sbc heads on the 6.2L i just checked out my 6.5L (same heads as a 6.2L) and compaired the bolt holes to a 350, not even close to the bolt holes of a diesel. and as a few said here make sure your asking a question thats actually possible, as in do your research.

Spunk.... I thought about this for about 10 sec, once.. then turned over a SBC head and a 6.2 head... thus forgot about it.....From someone who has worked with both the SBC, the 5.7 Diesel(predicessor/experimental prototype to the 6.2) and the 6.2... and from some one who has thunk outside the box about manythings, and has done what they said couldnt be done.. I will give you encouragement to try it... but the 6.2 is a totally differant animal than a SBC..... the heads have differant bolt patterns. differant head/block deck angle...(more like a Pontiac big block) not to mention finding a distributor to work in place of the vacuum pump would be virtually impossible.
the 6.2 reminds me of an old 60s big block pontiac with the way it is put together... they are yes one of the simplist engines know to man.... I love mine..... folks have told me it was a boat anchor, and I came back and showed them later.... but I didnt wag it in there face.....
Now as for you ailing 6.2.... if you do your home work you can rebuild that engine for approx 3,000.... I locked mine down last year and came out w/ 2300 in it.... as for power mods,,, there isnt really anything on the market.... I would recommend installing a 6.5 Turbo (this will remarkablly wake that tired old sluggish 6.2 up and make it stand up and talk....) just remember that 14 is the majic number for boost... anything over this will blow the heads or snap the crank.)) chances are your injection pump needs rebuilt and that is the main trouble with yours. if you choose to install the 6.5 turbo... find a GM 3 from the early 90s with the mechanical waste gate, then cut the regulator can off and fab in an adjustable rod... the stock turbo will get you 2-5 lbs of boost,,, shortening the rod will get you up the scale... then fab in your 3inch exhaust till you get past the T case,, then go to 3.5 or 4 inch... Now you will have a problem getting the 6.5 Rt hand manifold to mate to your 6.2 head... thus use 6.5 injectors and lines.... or you can have a machinist mill you a spacer in the shape of the manifold gasket out of 3/8s high temp steel or stainless.( I lucked out here my brother is a machinist for a plastics mill) Now I would recomend using clevite bearings and Perfect circle rings... Fell pro gaskets or as far as head gaskets go look into a Copper or metel High compression gasket... due to the added boost... Remember when assembling to use locktite on ALL CONNECTIONS IN THE BOTTOM END Rods main caps... etc... I looked into Main studs for this and almost bought a set for a 454 BB but used the 6.2 bolts for time sake.... Definatly use ARP head studs (availible from Summit for approx 150.00) or you will have a blown head gasket.... as for the crank... have it X rayed.... Yes I said XRay... I didnt and in 225 miles after a Brand new engine... my crank snapped in half one cold dark piss pouring rainiy nite 85 miles from home. I now have the last known NOS GM crank..... a remanufactured crank is junk... these engines have a special treatment on the cranks,, and once the crank is ground or repaired that treatment is gone... your bearings will chew through it in a fairly short time frame......Also... dont forget that in a SBC the piston depressions are Valve reliefs... on a Diesel they are injection chambers.... To late at nite and too many beers I made that mistake and had to tear all my work back down.
Another option is to get a 6.5 and do the same to it... the early mechanical injection 6.5s use the same pump... just w/ the internal fuel screw turned up a little... which is something you will have to do if you install the Turbo.....
As for the Hard to start.... check your Glow plugs... if its warm weather such as above 75 degreees... I will be willing to bet you that the previous owner was using either.... the curse of the 6.2..... dont ever use this stuff on a 6.2.... it destroys the glow plugs.
I was blown away by the milage and power that I gained by keeping the 6.2 and turbo ing it.... I run a Full 1 ton 85 crew cab 4spd w/ Ranger overdrive/ 205 and Before the Ranger goes in Im getting 17 mPG On 3.73 gears here in NE Wyoming around Devils Tower and down in the Rocky MTns.... once this Ranger OD goes in... my Milage will go up.... as for now even w/ my gears my poor Diesel is Tached out.... Rapid Diesel in Rapid City SD has some Mechanical Tachs that goe on the Flywheel.... the electric Altinator versions are junk... but finding were your power band and torque band are versus your EGT,,,, Exhaust Gas Temp is... you will find your optimum power range.... H\
Hey,,,, Cool down a bit and if you have any ?s feel free to ask...

Wow that was chocked full of good info. Hard to read though, but informative nonetheless.

Dude, I'm still think it could work. Might require some time with a cut-off wheel and grinder to make the heads and intake fit, but the parts are all free, right??
I guess with the right amount of moonshine and a banjo anything is possible! I also like the part about "free parts". Guys that usually think like this are always fixing there shit because it brakes down ALL THE TIME. A better question to ask yourself is: What's MY time worth.

I think you need to redirect your time/imagination to more constructive things, like say, I don't know? Fixing a 6.2 diesel instead of reinventing the goddamn wheel.

6.2Blazer is just being a troll

working on it, not a expert yet...i am going to wyotech next month so i will be closer then.

but i still dont have a valid reason why this would not work. all a 6.2L diesel is a small block 350 with a 400 crank aka 383 stroker, also from what i understand it has bigger bearrings and stuff. still not seeing a reason why it would not work. i know monkeying around like this is not what most people do or think of doing, i will probly not even do it, BUT i think it can be done. and will continue to think so until i a presented with evedence to prove otherwise, such as camshaft compatabilitys???(just thought of that)

I know about the high compression but thought that sence the original chevy diesel were the 350s thought that with the new head the compression would be closer to normal. anyone now how big the combustion chamber it on a 6.2L diesel head??

On the note of the distributor the vacume pump is ran off where the distrubuter gose. i think
dude dont say this at wyotec..
did you check your spark plugs*
the displacement for the diesel is like 379. none of the parts are interchangeable well besids the air cleaner lid and what not. think of it this way your asking how to put your sbc heads on a windsor... your thinking of the olds diesel eigine wich i guess can work with sbc heads but what do i konw.

ok first off you have no idea how an engine works, whether gas or diesel. diesel engines fire on compression, have no spark plugs, distributor or anything.

Wow, apparently someone is not smart enough to see the sarcasism in my post.

I thought that the mention of using a cut-off wheel on the heads to make them fit and the 0.200" overbore pistons would be a dead give-away. Since nobody else commented I guess you are the only one too retarded to know the difference between serious and sarcasim :flipoff2:

wcuhillbilly should be the only one posting in this thread

Thanks Camo..... Ive been through the wringer and have taken other peoples trash and made it my transportation for a long time...
I open this up to alll who have 6.2/6.5 diesel ?s .... PM me and Ill do the best I can to help....

Hey, I thought I was being nice.

No kidding, I thought you were too.

I just started selling these but I have a set of spark plugs that will bolt into the injector holes and I use a pressure valve where the glow plugs were that will reduce cylinder pressure by relaeasing some of it on the comp stroke. The gm distributor drops right in and use a hollley 650 dual pumper and away you go.

I like how the dude is calling other people an idiot! And dont the 6.2's actually have like 21:1 CR? Let me know when you find a cam for a 6.2 that has the proper distributer drive gear.

I like how the dude is calling other people an idiot! And dont the 6.2's actually have like 21:1 CR? Let me know when you find a cam for a 6.2 that has the proper distributer drive gear.

Ya know I was thinking around the second page that your distibutor hole on your manifold is gonna goto where? I'm far from a mechanic but does the distric go down into the block and mesh with gears on something(I wanna say cam) to time it?

So your distrib is goin to nowhere, your redrilling your 6.2 block to take sbc heads. Did you ever think that once you drill that block to fit those heads I really doubt your intake manifold will bolt up seeing as how that block is probably alot bigger than a sbc...

We used a couple of 6.2 blocks for ballast in a tugboat... did pretty good for that.. and the heads make good trot line weight in the river but are a pain to get back in the boat when it is time to move the line to a different spot... :D


































:flipoff2:

hey spunk, my balls have apparently dropped cuz im back

but where are you?
hahaha

you said you know alot for your age, well im 18 and a freshman in college and know that you know next to nothing, aside from MAYBE how to change your oil, from the looks of it from your posts.

you even went after some of the guys who were being nice.

an excellent way to use the resource that is PBB, piss everyone off and look like a retard, then sign back up w/ a different name later once you realize how dumb you are so that no one knows your back

piss off and dont call me an idiot, becuase clearly you personify the word
