Marcalan: I'm figuring a 331 cid with AFR 165's. Heard that 185's on a 289/302 would cause low-end torque to suffer. Need to verify.

ack_fia: ERA specifices 302 vs. 351 headers. Mine are marked 302. Did you have 351 header collector cut by 1", or did you do that to a set of 302 headers.

imagine2frolic: My goal is 370-400 fwhp. I figure a KC 331 or 347. I plan to use this mainly for spirited pleasure driving, with occasional open track use. I'd like to keep the noise somewhat under control, but I want to hear the rumble. I don't want to restrict it too much. In my mind, louder is better, as long as I can throw a Supertrap on it to mellow it when I need to.
