Around how much engine hp and RWHP would a 94 Gt auto with the following mods have?(94 cobra heads,cam,intake,roller rockers and injectors),CAI,pulleys,Full exhaust,4:10's,shift kit.
With this setup are 13's possible?
How much is it to port and polish heads? Is it worth the money?
Going by mine, which is relitively similar cept a 5 speed, I'd say with the auto they'd be looking at around 225-235 @ the rear wheels on a good pull. IMO screw porting the heads since it's so cheap to just buy new better alumnium ones compared to the cost of porting the stock cobra heads.
