500+BHP.. looking inside the belly of the beast

[fastco]

Hello we've all heard it a 1,000+ times..@ a car show or just crusie'n "Hello mate how much BHP in your engine mate?" Right well she's 500+BHP easly.... she's a 355cid Chevy V-8 & got 9.1:1 comp , .470 lift cam, double roller chain, race'n oil pump ,heads are GM Vette heads fellow told me were totaly reworked & would flow huge #'s to feed my beast. Intake is Ed's Performer & Ed 650 CFM carb , Dizzy is tricked out GM HEI... she's got the works mate.
We i'm sorry but there is no way on this gods earth any engine similar to these will produce anywhere near 500+BHP maybe 240 to 325 BHP....

Anyhow to give you a 1st hand look @ what it takes to build a 500+BHP engine / street driven engine . I'm thinking of posting a photo by photo complete built from scratch 500+BHP street engine. That would take you from bare block to complete turn key ..this would give people a heads up on what it takes to build that kind of engine & what parts & operations are needed to get the job done & make the beast last in a street driven car. . Question is would people want to see such a posting? Feel free to leave me your comments PRO or CON.... If more Pro i'll post the build.
Cheers! Dr.Dee

PS: Build is for Ultima GTR for street & track use

That spec looks pretty impressive, never had a chevy in bits are they a flat or 3 plane crank? and how long do you reckon, start to finish with the build.

Hello mates thanks for your positive responce on posting a look inside the belly of a 500+BHP street driven beast.
I will compile a photo by photo build of this bad-boy ... for now before i can complete a photo layout you can follow my progress as i start this build.
First & formost let's have a look @ the ally heads by Strike Force USA these are up to the job of feed'n him a healthy diet of air & fuel heads intake runner volume is 215cc these heads as you can see are 100% CNC machined & ported & chamber blended & intake gasket matched.

Dr Dee,

Like the pickies m8, the valve guides look like they still need blending in a bit,
do you hand finish them after CNC'ing.

Hello Mark... good point on finish sanding and blending ect on valve guides & bosses & chambers & valve bowls ect of these heads... and indeed i would load my die grinder & spend a few hours on these .. but the key words here on this build are the words budget ( very tight @ 4500 P/S) & off the shelf parts that were going to use....the parts used are as ordered with no hidden extra tricks / time & money spent.
We've all seen those wonderfull magizine wright ups on engine builds & dyno pulls with the dream team of engine guru's & tons of free bee parts supplied by manufactors ( bring'n there tricked out best of the best parts to the build see American Hot Rodder or Horse Power TV on the SAT )
Thats all fine & well mates... but in the real world for us work'n chaps were going to stick to a no tricks budget plan.
Cheers! & Best reguards!
Daryl aka Dr.Dee.... cross the pond
