66 cuda project begins

the transmission is a four speed, factory. is it ok for some HP. I just crawled out from under this car, I cant believe how solid it is, drivers side floor pan will need replaced, but frame rails and whole undercarriage is solid, no rust, well...very little. the hood was crinkled, look like it came up while driving kind of thing, but I drove to Houston and picked one up for 125.00. the used one is arrow straight. need some chrome stuff, been shopping here for stuff.
