How much HP?

[King Cobra 22]

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.

Don't use a Cobra cam! They're worse than the stock GT cam.

So it would be better to keep the GT cam and just get the cobra heads and intake?

It would be better to get a different setup all together, but it depends on what your goals are.
