I have a 93 trans am with a flowmaster exhaust ORP with 3 inch pipe and a K&N filter and headers. I am wondering what the biggest cam is that I can run with stock heads. I also have a PCMFORLESS chip that I can send in and get reprogramed to fit the cam.

 

i use the comp ex224-230 and did a mild clean up on intake and heads. nice power .just taking a break from the street twin install hope to get to the track next week looking for some improvment.
