That's why I was asking him about his 60' time, but 2.1 is really good for a GT. NA cars generally don't get 1.9-2.0 short times without lots of mods and/or drag radials/slicks. Just don't have the lowend TQ.

A 93 MPH trap is pretty good, trap speeds are a better indicator of power output than ET's. Did you happen to put your car on the scale at the track? My GT weighed in around 3400 lbs. w/spare & jack removed, GTP was over 3800 lbs.

Best way to make more power in your case is to tune. Add timing, lean out the 02's as much as possible (as long as you don't have KR), and make sure your LTFT's are locking 0 in PE. A set of S&S headers probably wouldn't hurt, either.

You'll be a lot happier once you get an L67 though. Had you put the same money into a supercharged engine, you'd be low 13's for sure.
