a 460 with a c-6 would be easy, but as usual Tech has the idea that makes way big torque and excellent driveability. Wish you would quit mentioning them 500 Caddys, Tech. Now ya even got me looking for one!!! See, I know where this 53 Ford tudoor is, and with all them cubes and all that torque...........Just gotta keep it hid from Streets or he'd have to put one of them chebbies in it..
