haha nothing near a stock cam. It's been a while but I believe its something around a 232/240 .590/.595

As far as running low timing or a methanol kit I just have the car tuned on 100 octane, though I could prolly run a little more timing with 93 and meth I just feel safer running 100 all the time and not using meth as a sort of band aid for fuel.

Thanks SSprayn, those are some great numbers also, I would love it if I hit some where around there, althou mine is a 350 ci, my cam is right close to yours, my heads are still stock for now, 9.25:1 cr, 61mm t70, with forged pistons and rods, and if I bump it up from 6 psi (which I have at 2500 rpm's) to 9 psi, desk top dyno 2000 says I should have 642 hp @ 6000 & 700 lb ft @ 3000 rpm's, do you think that is very close to what I should have?

Although I'm not as familiar with turbo numbers I would say you would have a good shot at making numbers close to mine. The stock heads may hold you back some but efficient fueling and a good tune is the key to making the bigger numbers w/o a ton of boost.

Also it depends on the tranny that you are running as well. For me running a th400 kills alot of HP. I have no doubt that if I still had the 6 speed in the car and a intercooler I would see close to 750 rwhp.

If you have a 6 speed I would def say you have a good shot at making mid 600's

wow, yea, I have a six speed, that just put a grin on my face, although I still have 3.23 gears that need changed out, mine is a 93 with no maf, and I am going to get ahold of pcmforless to burn me a chip for now, untill I get a stand alone. thanks again SSprayn!

I only have 3.42 gears and even though my car is a 94 we did a speed density tune so it has no MAF as well. I am friends with one of the guys down here that does PCMforless, he has been working with bryan for a while now.
