Trying to get a number in my head as to what this combo is going to make at the tires. its in a 95 Corvette.

3.90 stroke .030 over LT1 (399ci) callies magnum lightened XL crank,oliver billet rods 5.85
AFR LT4 heads around 330cfm at 600 lift. not alot higher at 700
solid cam 650/643 252/256 at .050 111 lsa
LTCC conversion
mono blade throttle body with some minor work to it, 1350 cfm
heavily ported lt4 intake
Ross 12.9:1 comp. runs great on 100 octane so far
Cai
factory MAF
1 3/4 long tubes, x pipe, no cats, dual 3" all the way, SLP mufflers
50 lb injectors
aeromotive A1000 fuel pump,custom -08 rails
4.09 gears,6 speed,centerforce dual friction,lingenfelter lightened camaro flywheel


thats all i can think of right now...i would be really happy with 475 rwhp N/A. is that attainable? the motor was not meant to be super strong N/A. the throttle resonse in unbelievable

Great flowing heads, huge solid roller, light crank, and almost 13:1 compression. I would say that 475 is probably a conservative number and that you really have a good chance at hitting 500!

I think an agressive 399 ci solid roller car if done right shoulh make 475 or up to 500.

Wow, put up a video of that beast!
I think you will hit 475 no problem.

Lets see some pics!

Sounds like a beast, and I agree with MPE331 and Pauly, you have a chance to hit 500 with the right SR grind and some NICE heads... AND you already have both.

I would expect 500 area with what you have posted being a manual trans.

Are these the eliminator heads?

I would think you should be approaching the upper 400's to 500 area.
