  1. Drivetrain & Performance
    I need some help picking a motor for my '73. Right now, it has the factory 250 inline six, three on the tree, and 3.08 rear gears. Eventually, it will get 3.42's and a Keisler RS400 five speed, but before that happens, I want to decide on a motor. The main thing is that it has to be good on gas...
