can anyone help me out with how much hp this set up will make?? trying to decide wheather to build this or throw in an lt1...

1987 gta 350 tpi, bored .30 over
3.23 gears
10.3:1 compression
holley stealth ram intake with airfoil
comp xtreme enery hydraulic roller cam: 224/230 duration, 503/510 lift
hydraulic roller lifters
comp magnum roller rockers: 1.6 ratio
double roller timing chain
torque converter: ~2500 stall
3" flowmasters (thinking of changing)
Edelbrock shorty headers
might be getting heads

I was also wondering if anyone had some suggestions on good compatable heads and cam. im looking for around 350 hp with the above set-up. I really want a good sounding cam, but i have tpi so i dont think the lobe seperation should be less than 112 degrees.

Thanks a lot for any help!

You'll need to ditch the stock heads if you want any power out of it. My bud has a very similar combo in his 3rd gen, only with a 220/230 cam and heavily ported aluminum L98 heads. It's runs gooooood.....by my well calibrated butt-dyno, I'd say sneakin up on 400hp. :)

hey thanks for your input.

does anyone have any recommendation on heads and the best size cam to go with them? im not looking to spend much more than 1000 on heads. i heard edelbrock heads are no good... true?

Patriot Performance heard are about 800 complete, they're decent.
