Seen this build on superchevy.com

I only its shy of 600 horsepower and torque but I was thinking maybe a Xtreme Energy, XR300HR from comp cams, with some 1.8 rockers and stiffer valve springs. Or i could used a Lunati Voodoo Retro Fit Hyd Roller Cam Part Number: 60212, High RPM Hydraulic Roller Lifters P/N: 72531LUN, Voodoo® Roller Rockers - Chevrolet (396-454) 1.7 ratio 7/16 P/N: 85350LUN which setup well make more power and still live on pump gas i have 94 octane. This is a daily driving engine in a HUGE 4x4 thats why i picked everything rollered and balanced but whats the power i could expect? I might do 10.5.1 and 102 octane but lets keep it at 94 octane.

I'm thinking about a pair of AFR 325cc As Cast Magnum BBC Cylinder Heads instead of the partiots and a single plane intake from dart should give me the numbers i'm looking for oh yea i ahve the block and is good so its cheaper building a 496 instead of buying a crate engine 502 and building an engine yourself gives you peace of mind knowing its done right

You may build it right, but the 502 would have a warranty. If I was building it I would consider going with a

good bottom end and blower. That would be awesome. Our mailman done his 454 in his old Chevy and the engine was basically stock other than a good bottom end, heads and his engine produces around 700 hp.

ahhh the fun of bench racing. ok, lets eliminate all the parts that WONT add to the horsepower...but will just help contain it and leave only the parts that actually do anything...

I left out the parts that you only gave a price and part number on because I'm not looking that crap up to figure out what it is. I'm assuming the eagle specialties is either a stroker kit or rebuilt shortblock?



either way, you find the bore/stroke, take the cam specs, carb specs, expected operating rpm range, and what kind of torque conveter stall speed (if automatic) and plug it into one of the many many online horsepower calculators out there.



personally, if you're looking for a specific horsepower # without all the guesswork involved, buy a crate motor and fit it with the recommended components and that will get you really close to the crate motor's advertised #'s.

wow impressive parts list, by the time you get through screwing around you could have just bought a 502 that was built by someone that knows what there doing which would have put it on the dyno and told you exactly how much HP it was putting out, at about the same price, except it would have been built by someone that knows what there doing.
