300 hp, how close am I?
I know this subject has probably been beat to death, but I've done a search and couldn't really find anything definite. I have an '01 GT automatic with a BBK CAI, Accufab 70mm throttle body/plenum combo, throttle body spacer, and Flowmaster 40s. I plan on getting long tube headers and an off road pipe next. What else should I get to reach 300 hp? TIA.

Ported and polished heads, good cams, underdrive pulleys,a good set of longtube headers, off road x pipe, and possibly a 75mm throttle bodyif you're going N/A. Throttle body spacer a little more than a paper weight in my opinion.
Oh yeah a great dyno tune is definitelya must.

Oh I know the tb spacer is kinda useless, but it was cheap and I figured I might as well. The main goal for my car is to be able to run from my cousin's Gen 3 LT-1, T-5 Camaro. As far as I know he's got a mild cam, ported heads, and a chip. I think that's it.

Right now you are at about 230rwhp. You need full exhaust, cams, heads, 75mm TB/ Plenumand a good tune to even get close to 300rwhp.

STOCK he could be anywhere from 210-220rwhp. If thats the case you honestly think full exhaust would only net him an additional 10-20? From the stangs ive seen, full exhaust, tb and plenum, cai, and **** tune got my friend about 265rwhp, and that was with a crappy tune mind you. A good tune coulda had him 270-275ish.
And another friend of mine is doing the heads cam full exhaust route, and he should be seeing 310-320rwhp with em.

Full exhaust on its owncan get anywhere from 25-30rwhp. Depending on the tune, and of course youd need better flowing heads. With the latter 2, ive seen gains from 25-45. You will need the heads to get the full efficiency of the system, but still on its own, full exhaust should get you on average 25-30.
