What will my 430" make in my C5Z... ?? -430" (4"x4.135")
-PRC 265 LS7's (385cfm @ .600") @ dcr 11.75:1... scr @ 8.31:1... quench @ .041"
-243/259 ~.620" 113.5+4
-Kooks 1 7/8 x 3" .. no cats
-MSD Intake (light port/cleaned) w/ NW 102 w/ Vararam
-Morel .750" wheel, hi-rpm link lifters
-Manton 3/8" .095" wall pushrods
Hoping to get ok timing out of it... I would hope for 18-21*... have to deal with this California 91 octane.
Let the guesstimates flow...

Hi Scott
568 RHP, and 525 RWT.....What rockers you using ? can you use Ls3 rockers with those Ls7 small bore PRC heads? or had to LS7 rockers only?
I am going with similar 429 cid, 4"X4.130, in fact just got the short block from machine shop, but going with stock LS3 top end due to no budget left...lol, but eventually go with Ls7 top end sometime later...man our cams are very similer...243/255 111+3 Cam on HUC lobes.....-3cc wiseco pistons, callies rods, callies crank......pfadt 1 7/8 no cats........johnson SLa lifters....so on.
I think i sold 3.4" Aand A pulley to you couple yrs ago on CF?....
note: SC kit is sold, going NA stroker this time.

with 8.3 dcr you may be able to get your timing up there where it needs to be and still not knock. some combos around where your setup is are over 600rw so no reason to think yours shouldn't either unless they stay conservative. i'll say 590-600 rwhp with 515-520 rwtq. maybe if it knocks you can always throw in some octane booster or hook up meth.

Sami.. long time. You also sold me your livernois 243's, awesome heads... those are long gone, as is my blower combo.. lol
Here we are, big cubes, heads and cam... I think I'll like it the best. I was really hoping to touch 600 with it, we'll see.
Rockers are LS7's with the Schaub bushing kit.
