What kinda power am I looking at?

I have a very similar combo besides fuel injection: edelbrock performer heads, trick flow rockers and springs, BBK ssi intake, & long tubes. Not sure what cam is in the dang thing though. :crazy: Before i tuned it properly it made about 280hp on the dyno. (you'll lose a tiny bit on an auto) But it also made about the same in torque... And that's where the bite is. I have 3.55 gears on a T5 and shoot, it snaps necks with some good grip. More than enough for a daily in my opinion.

Umm, that’s not similar at all.
 
Aluminum vs Iron heads make a big difference. Your car is making pretty standard (not bad) numbers for your setup. If his car put 280 to the tires with a gt40s and a b-cam, well I would drive mine off a cliff.
