Want some tech well here it is, i decided to put a roots blower on my 266( it will fit a 304 also) on my 1964 c1500. The first thing i did was purchase a rpt manifold from ih only, and make a plate to fit a 8v92. I chose the 8v92 because it uses the same covers as the 71 series but bigger bearings and a slightly smaller bore(displacement). Although i dident take a picture we used the plasma to cut a plate of 1in aluminum out of a 4 by 8 sheet and then started machining.

This is me setting up the parting tool on the van Norman horzontal mill.

The to sets of bolt patterns i am putting on the plate, the narrower pattern is the v series blower pattern, the wider is the straight serious blower pattern. I decided to put both on for versatility.

Hell Yeah!! this would be a nice mod to the 266 in the trail rig. Sir you have my attention!!:smokin:

VERY cool. You have my permission to stick around:D

Sweet

Holy best 1st post ever!!!

I like it.

um....freaking awesome!

on a tuesday?

Normally a good post results in eventual failure. Well see how this goes.

Where did this guy come from anyways?
Great tech, we've been needing this...
Are we sure that this is Tuesday?

:eek: You'll put yer eye out kid!

I hope it works. then we can work on a 345/392 version!

I already paid for all the parts i need, and i have plenty of time to get this done.

I orderded the 304 propane gaskets today, i havent confirmed it but the propane gaskets are supposed to block the exhaust cross over. The only thing i would still like to buy are these rocker arms, and some 304 heads for the bigger valves.

Dan, you've never seen those? They've been around for years. I remember people talking about them on BB 2 years ago.

Also, 304 heads on a 345? That's different, isn't the difference in deck heights going to be a problem?

Cool, I say go for it. This is the first root style SC build I've seen, but someone on the BP is using a centrifugal. I like the project and am interested to see it done. I just see it floundering in some mud truck and wonder what the planned purpose is.

So what is the intended purpose of the above mentioned c1500?
















If that doesn't work out there is a smokin deal on a grate truck on RI C.L.:flipoff2:

I already paid for all the parts i need, and i have plenty of time to get this done.


How is your motivation? :flipoff2:

the c1500 is my party resto rod, swapping out the 17in rims for 22.5 and building a bed with a built in grill, keg, and wet-bar.

I think im very motivated considering i pulled the trigger and bought a 500 doller manifold and took a end mill to it right out of the box.:flipoff2:

big thanks to Ih only for building those manifolds they are top quality

I'm in, I am looking at a blower for my 34 C1 short box pickup. I am looking toward a sheet metal manifold for a 392. I will be watching your junk, rite on time for me. What is you budget for the motor build, I have been looking and seems to me the blower set up will add about two grand to my motor build but the cooool factor will be well worth it. I am doing my hotrod this winter. And welcome, way to kick the door open and set us web 4x4 guys on our ass:eek: You have the floor sir:flipoff2:

Any idea on boost limits for an SV? Must be up there.
I've got some superchargers laying around, little bigger than M90's that I've always wanted to slap on the 345.
How much boost did the old turbo 4-cyl scouts run?

IDK about boost numbers, but the crank and rods are pretty beefy, I bet with some good head gaskets one could run quite a bit of boost.

Im going to port the heads out and install bbc springs and Murphy rocker arms i am currently looking into some custom push rods that are a little beefer. The engine work will not cost much since i can do it myself.

The eaton line of superchargers is a good idea, but i didnt have one at the time and i purchased the 8v92 for 50 bucks. :flipoff2:

Does anybody have the center to center rod length for the 266/304 engines i need it to answer the question about boost pressures. Using the dynamic compression ratio caculator i could give a theoretical max boost, but whether or not the bottom end could take it is more of a practical issue. :confused:

If I remember it was pretty low, like 4-5 pounds.


Edit:
Found another thread where a dude talkes of running 7-10 psi through his 392.... Seach "scout boost"

I'm sure you are going to have to under-drive the hell out of it in order to keep the boost down. I am overdriven just a little with a KB 6-71 on a 490 Ci BBC. I hit about 10lbs at max rpms.

I was going to install an Eaton and a intercooler on the other SSII, but, I think I may take up desert style racing with it next year. So that is off the table.

like i said its all pretty much speculation until you calculate the dynamic compression ratio, that would tell you how much boost you can go without spark knocking.

As for the drive ratio i am gunning for about 10% under driven.

shawdow man did you say you have a kenne bell, because you said it was a 671 and i thought all kb's were screw type not roots type, i would like to see a picture of the blower it sounds cool!

were also running a 6200lb pulling truck 557bbc, 1471 high helix, 50% overdriven, re striped it makes about 42lbs of boost. :flipoff2:

Keith Black, teflon tipped rotors in the 6-71 that is on the BBC. I have a spare Weiand 6-71, a Eaton and a intercooler that I have sitting on the shelf.

Are you going to run an MSD BTM? Or some form of boost dependant timing?

After TBIing my 345 and turboing my 1.8l Honda I have often considered turbocharging an IH motor. I run 10psi on my 4cyl and make ~250whp... about a 100hp gain. Compared to the Honda motors the IH engines are straight beef. I would think they could handle 500hp easily... so long as you could pull timing / push fuel accurately enough to fight off detonation.

Can't wait to see this thing run, vids are required.:smokin:

Exactly! That is why I don't compete in the Big Scout.

I would really like to see a supercharged IH motor on a dyno.

There is exceptions in some desert race organizations, but I believe it is for CARS that are factory turbo-ed.

I know there's a vid floating around of a 345/92 with a blower on it on the dyno. The one that's in that mall crawler that gets posted every now and then.

I know when I was still on the BB every day there was a guy planning on turboing/twin turboing his SV. No idea if it ever got done though

I posted that dyno video in another thread, I forget which one though.

The only other forced induction SV I know of is Chief's turbo motor.

This one?



YouTube - Blown 345 IH Scout Motor Dyno (http://www.youtube.com/watch?v=IqdYVwVrX1E)

My point was he can run boost, it just has to be a diesel. Basically I was trying to convince shadow man He needs to build a diesel powerd desert scout.

Yota Lay off the post button before you F*ck up this fine thread.

Is there any known record for most power from an IH mill?

probably need to be from an MV, or is there a BV?
saw my first 404 MV saturday, looked just like a 7.3idi

i run 8lbs in my 345 and its a sweet surge of power i have had it up to 15 lbs and it was more like and explosion of power but i think i was getting pre ingnition and im sure something would :nuke:

LOL, an MV really? 392's made more power then a 404 MV, and MV is still a small engine by international standards. MV's are CRAP, they run hot, but hot and eat exhaust manifolds like the are candy.

For an SV, I don't know if anyone would keep track. My guess would be Davesr's pulling 392.

So much ignorance in 2 little sentences:eek:

To the OP, it looks like a cool project:beer:

I'm sure you know boost will be limited by dynamic compression and fuel used......I didn't catch if you said what fuel you plan to use?
:smokin: Project.

since i am going to install a kegarator and a grill i was thinking propane, but i will probable go with multi port fuel injection, and 87 octane pump gas.

Might just add some methonol to the mix:flipoff2:

Get on youtube and look for a video on a blown 345 IH. There was a feller with a built 392 who used to do truck pulls, that was a bad ass motor.

that 392 was Davesr that Diesel mentioned above. IIRC it was pushing 450+ horses, and the whole truck sold for <$5k:eek: Thing was amazing, and if it hadn't gotten 1mpg I would have sold my scout and bought it. He had a hell of a time selling the thing I remember, because I dreamed every time there was a price drop

Yeah, that one! I saw a video of it in action. He made a full pull and kept on going, the guy at the end with the flag had to run for his life!! :laughing:

Why can't numbs get this, awesome first post. Bring on the tech even if it has nothing to do with wheeling it is tech:smokin:

Sorry i cannot post any pics today, I forgot to charge the battery's in the camera because i am a dumbass! This weekend i mocked up the carb spacer to the rpt intake and started getting ready to mount the the plate to the intake, I havent done any cutting yet, but it is looking good! the blower is about the same length as the block, and the drive i have looks like it will fit great, i was then sidetracked by a wood fired boiler me and a buddy are building.

I also had a chance to look at the bottom end of the 266 that i recived for free, it looks tighter than the engine that i have in the truck.:eek: I think this will be the engine i will build to get the full potential out of the supercharger.

oh by the way the max boost for a 266 using the dynamic compression ratio formula is 8lbs with premium or about 6lbs for 87 octane i am a low lander a 961 ft altitude

Edit: I will try to post pics before Friday!

i am a low lander a 961 ft altitude

pffft, I'm at ~36 feet and my parents house is at about 16'. Really cool thread, though. We're all sitting here hoping you don't run out of steam before you finish. :beer:

to the OP I am on the SW side of the city, if your looking for parts give me a heads up. I don't see much IH stuff at the boneyards these days, but I hear there is a yard off of I57 near kankakee with a number of binders

http://i915.photobucket.com/albums/ac353/64dumptruck/blowerbuildpics012.jpg

So where do you see the weak link and what do you recommend for improvement?

Too much overhang on the blowing mount that goes to the spacer. That blower is going to produce a bunch of tension trying to pull the nose down when the belt is tightened. I predict the aluminum spacer will bend. Or maybe the rear bolts will pull out of the spacer/manifold.

I see stripped bolts and bent aluminum in your future :homer:

awsome build! as far as the overhang issue, could you build some sort of bridge from the two front intake mounting bolts? up and over the water neck.sort of a truss system to make it more ridig,and any downward force would go to the block.

Thats what i was thinking, some sort of braces from the bottom on the blower studs to the intake mounting studs.

I did something similar to a 392 in a 2wd scout about 20 years ago when I was working in San Diego. I used an 871 blower. Anything over 6000 rpm snapped the crank snout off. We were 10% underdriven. Also I remember replumbing the water neck and not using a t-stat. We used a cast iron spreadbore intake.
The third engine ended up with no blower and a 150hp nitrous plate. No more broken crankshafts.

Fuck me running! What did you do to the valvetrain to keep it from :nuke:

As I remember, had a shop in El Cajon do the "valve job" using some big block Dodge valve springs?. I think it had some Manley valves. I do remember taking them back for a $400 port job and it made no difference. Also had a custom Crower cam(weld&regrind). I don't remember the specs. I'm sure they were small block chevy profiles.
