There's no better way to break in a new dyno than bringing new life to an old favorite. This time on Roadkill Garage, Freiburger and Dulcich refresh their junkyard-rescued 1971 Pontiac T-37 by removing the tired Pontiac 400ci V-8 and replacing it with fresh Pontiac power that delivers some horsepower and torque surprises when it runs on the shop's new dynamometer.
