what do you think I should expect with a tune?

Here is what I have:

LS6 intake
Livernois LS6 'Stage 2' 59cc heads - flow numbers below:GM MLS .51 head gaskets
Cam: 234/240 .599"/.610" 113 LSA
Diamond -2cc valve relief pistons
Compstair 6.125 rods
Stock crank
LS1 3.905 bore

Those heads flow better than advertised huh. I am thinking of going with those too as the low to mid #'s are very good for a GM casting and they don't hog out the intake runner but keep it around 220cc. To answer your question I think you will scare it but that 9" will eat up too much to get you there. A fast 90/90 would get you a little closer too. Good Luck!!!

Highly doubt you'll hit 450. I think you're going to need the FAST

LS2 vehicles typically make 450-460 RWHP with these heads, our stage 2 232/232 .595/.595 114 cam, and LT's with a stock manifold. You may need a FAST manifold to reach this number with a stock bore LS1.

Numbers and Mods in My sig, I reached 480 with LS1 heads, cam, Fast

I think you should be over 450, if not it will be due to the intake.

I plan on getting a Fast intake and 90mm TB when I get extra cash. For now I will sit on the LS6 intake and hope for the best numbers. I'll keep you guys posted when it's all done

I fell about 5hp short of the 450 mark but, Im still happy with the car. The mods are in my sig.

I would say that it could be done. i put down 420rwhp with my setup

I would put you at about 430 to 440 RWHP with that set up and without the Fast...With the Fast i think you will be alot closer to your mark of 450.

Based on my results...I'd put you at around 430 on a dynojet.

i agree, i'll say 430-440 now and with a ported 92/92 (if you get new since 90/90 is discontinued) 450-455, possibly 460. just guessing though.

Yeah your gonna need a 90/90 if you want to hit 450. I don't see it being a problem once you get that.

I thought so, for now it's the LS6. I should be close with the size of the cam I'm putting in. Flow numbers on the heads were better than the Stage 2 Patriot LS6 heads

you should be able to but you could have made that with cam only if you got a vindicator

Wanted at least a little drivability..

I have ran that head personally (but on a 64cc chamber) and a smaller cam. I think you will be quite pleased
