No, not yet. The rear is 7.625in open rear. So I basically spin down the track with one wheel. Hopefully I put an 8.5 rear and new driveshaft. Not sure how the heads will do at high rpms either (run out of breath). I would like to do an LS2/T56 eventually. Maybe twin turbo build. But that is a lot $ and time from now. So many possibilities, but I want this to be a pro touring type car built for twisties.
