Has anyone put any power to one of these at the track in a (somewhat) heavy car i.e. 3600 or more? I am really having struggling on getting out the sawzall to hack up my original floor pan for a Lenco.

I don't mind maintenance or a pro shifted box on the street. As far as the clutch is concerned that isn't a huge deal for me either. The more I think about it the more I'd miss the h-pattern shifter if I go with a st1200.
