My guess is that he meant 5.2 0-60. 350 or so hp, 3100 lb car, geared right...that sounds about right.

Making it handle better, that will take some doing. About the only thing the handling needs is rack and pinion. That would be a major improvement, otherwise the usual things would compromise ride, like stiffer bushings.

Problem is, the Supercharged version will probably be north of $40K...
