Earlier this year host Mike Musto made a post about how he wanted to put 10,000-miles on his 1968 Charger in 2024. There were comments and questions, but not so much about the miles, but more so about the engine and drivetrain combination. The specs on the engine are mild. A 440 cubic inch big block with iron 906 heads that were bored .30 over, a 470 lift cam, with an 800 double-pumper on top. The transmission is a 727 with a reverse valve body mated to a gear vendor through an 8 3/4 rear with a 3.55 gear – as for power though, Musto really had no idea what the old lump made.   Enter Hemmings own Evan Perkins, our resident engine guru. He suggested that Musto throw it on the dynamometer at Westech in Southern, California, a mere 450-miles from Musto’s home. Not only would that tell him the power output, but as Perkins explains, using a dynamometer is one the best ways to tune your vehicle and possibly even get some extra power.
