maybe? i mean, it'd be interesting to see an analysis on computer modeling/software of what could be. i forget what the the finer specs of the cam were but if i had to do it again i'd probably spec something out instead of grabbing an off the shelf grind.
but i think it's mainly the architecture of the motor in that you really gotta spin those small bores up to move enough air, and that comes at loss to low and midrange which is only magnified by the already anemic lower rpm numbers.
if you were specifically building a car to go jackass around in and you had most of this stuff laying around it could be real fun (and probably make you a nice bundle of money)-- especially with some steep gears and a 4spd or a bunch of stall.
