1979 C10 Bonanza. The exterior of this truck isn't touched since my great uncle bought it off the dealer lot in '79. I'm a third generation owner of this truck. Right now, it's all motor and tranny. We dropped an '87 350 in it rebuilt about 5K miles ago with a stage 1 aluminum intake, holley carb and a higher torque cam. The tranny is out of our old '78 van, rebuilt about 15k ago.
