454

[glosasso]

guys i have a 454 i would like to build.. it is a piece on a stand right now the build limit is 2500 i would like to build it from the crank up for a reliable high horse power motor. could u guys throw some different combos for some good power out there im new to the big block world.

[trkklr77]

scat crank
049 or 781 heads
.500-575" lift cam
fllat hyper utectic pistons
performer or rpm type intake
750+cfm carb

300-450 hp depnding on cam and piston choice, the rest will get ate up in block prep, balance, assembly, small parts, gasket set, oil pump.......


you can build a lot of a bbc with $2500 or you can go insane depending on what kind of buddy deals you can get.

[glosasso]

i got the intake carb and pistions i need a crank and rods how many rps can i expect this to turn and would a litle 142 blower or anything effect its reliablity

[glosasso]

im lookin at a set of brodex heads someone i know has too so im hopin for a high horse reliable daily driver

[trkklr77]

depends on what crank/what rods you get and how well you can oil the whole thing.

most people run out of oil long before they get into the range of centrifical destruction.

the little 142 aint enought to feed a 454 and a 177 isnt much better, youll make more power but you will still run short on the ability to feed it up high.

so you have a 2500 cap and you want a set of brodex heads........ well i guess they will look nice sitting on the shelf because you wont have enough to finish the motor.


and scooter, high horse power and reliable daily driver dont work. you build a 600hp motor and it wont like the street for long.

[glosasso]

listen the 2500 was just a roundabout im thinking high volume high pressure oil pump and even if i dont get the heads and just do the motor then a blower 6-71 or something if its done right would it be reliable? as far as just putting from school and back and around town maby 30 miles max a day

[glosasso]

itsin a truck with a 4 speed and 538 gears with 44s

[trkklr77]

you were doing so well.....

Man are you losing your edge or getting soft? Your being so nice WTF?


Hey search. super chevy, car craft, engine masters,and hot rod to name a few. I bet you one of those mags has a budget build on a BBC right now at the news stand.

[trkklr77]

his first thread was a complete cluster fuck, he got ripped and hgtd'd. came back with a very clear and readable post, fine, he put in some effort. then he started tripping over his parking lot pussy getter wet dreamer complete with back pedal and the best parts he can think of no matter how much he doesnt need them...............

[sjracer]

^^^^so true^^^^

let's see-
if you could separate a set of un-whooped broadix heads from the hands of some tweaker you might score them at around a couple three four hundred, and the tweak will score a fat rock for the night.

then lets say it's a freaking perfect world and your block needs super little work to get it ready so there's another grand or so.....then your gonna need gaskets, a good oil pan, windage tray, oil pump, cam, balancer, flexplate/flywheel, upgraded main caps, oh and don't forget the really loud gear drive for that "racetruck" sound.

and if you would actually pick up some books first such as "how to build a big block chevy" you be out a very smart $20.

because then you'd realize that just lumping a bunch of mismatch parts doesn't guarantee HP......or longevity.

but hey, we all need to dream i guess.

[Grumpy_old_fart]

Im a dreamin of some big chiefs for my motor.... someone talk me out of it!

i can put em on a low compression 366 and make BIG POWER on pane...

but only if i use a tunnel ram and a single propane unit on top of it... like an IMPCO 425 or so...

wait...

better idea!

I have this 454 with 121 cc peanut port heads and a Profiler intake with a dominator and a huge roller cam with about .790 lift and 285* duration at .050.. I think itll work! Do i need pistons with a bigger dish?

ohmygod... shoot me now!

[K5runner@hotmail.com]

Ha Ha I don't think he will be asking that question hear again.

With a 4 speed, 538's and 44's, you better have bead locks.

If you buy expensive parts it they will obviosly work well together.. Right? this guy reminds me of my buddy.. 496.. barely 10:1, older dart 345's(paid new price), 260ish @.050 solid roller, victor jr, 2 corner 85O holley, 1 3/4 headers, 2 1/2 exhaust, 2000 converter.. 3.73's, 37's... He cant figure out why it dies in gear, and wont even spin the tires.. hmm.. oh did i mention he's now broke and had more fun with a nearly stock 396?

[GMCTruxrule]

I rebuilt my 454....total parts and machine work cost put me at $4200. I do live in Hawaii, so its a tad more expensive out here.

Stock 702 casting heads, required a complete valve job, block blueprinted and balanced, new cam, pistons. Very reliable but very potent.

I think 2500 is stretching it for you. But if you are smart about it, you can also have a reliable street motor. Just no need for throwing high dollar parts at it.

[brokenparts]

yep I managed to build a decent 454 for about the same amount of money you are willing to invest... probably even less. Check my 454/049s thread here in this section.

[Burt4x4]

What is the truck/rig gonna be used for?

[sjracer]

hauling a trailer full of broken dreams to the wrecking yard.

Add another 2K and go EFI


I can wheel with my feet on the floor while climbing/crawling ..so again what is the build for?
