Am sitting pat for now as another big '65 Olds (that's 4 now) science proj...I mean convertible awaits re-assembly in my garage. Came with yet another spare 425 motor, think I'll swap that one into my 22" Craftsman.
Talk about Opportunity...I also recently bumped into and subsequently dragged home a nice complete (radiator to P brake)low miles early 1960's C30 drivetrain, a "High Torque" 283 and SM420 (with driveshaft parking brake) assembled combo out of a low miles RV.
Simply put, I want for nothing more.
