cross1; I totally agree on a little more HP but I disagree on the gearing - our cars have 3.27 ratios in them now and it gives a top end up over 145!!! I think with the lack of hp it would benefit greatly to go to at least a 3.7 or lower gear. I owned a mustang wsp pursuit car a few years ago, and it totally changed the character of the car when I went from 3.08 to 3.73 - fifth was actually usable below 100 mph, it closed up some of the space between the gears so the "R's" didn't drop so much. And the top speed actually went up to 145 because it was able to pull redline in fifth!!
IMHO
