If you run a
14.1@101 with a 2.7 60', that tells me your car makes good mid range and starts to fall off on the big end. My Z28 ran stock
14.08@99 with a 2.13 60'. Our MPH is close, yet my 60' is way better and our ET is almost identical. You made up ground somewhere, the mid range or you have a problem on the big end.
Nonetheless, that is a good running car you have.
