I have a 89 GTA 350 tpi with a auto trans. As far as i can tell it has slp runners and headers but the kicker is thier is a sticker in the bottom of the door that says Enhanced and tuned by gale banks. Im currently waiting on the paper work from them to see what all was done but in case it was nothing more then bolt ons, what are some good mods to get me in the high 11's? Im an old school carb guy but i vowed to build a fuel injection car without getting mad and putting a carb on it. I thought this would be a good car to start with as i am the third owner and the car is perfect inside and out it has been garaged its whole life and i got it real cheap because the person didnt know what they had and it has a spun bearing. All the info helps thanks.

Higher stall, 3200+
shift kit
150-175 wet shot of N2O
3.73 gears

Whats the biggest cam i can go use with out affecting the computer? Also is it worth porting the upper and lower intakes and heads or should i go after market?

Crane makes a compucam 214/220 @.050 that works well with the stock computer and can be run on stock heads IIRC. It's on the milder side, but you'll be hard pressed to run anything more radical on an otherwise stock engine. http://cranecams.com/?show=browsePar...tType=camshaft
