This 1962 Studebaker Lark stopped by Sloppy Mechanics for some dyno tuning. The compact car is powered by a 4.2 L Vortec 4200 inline-six with a 66/66 turbocharger. It feature a custom intake and exhaust manifold and runs off a Megasquirt ECU. The engine made 430 horsepower and 420 lb-ft of torque to the wheels on 14-15 psi of boost. The drivetrain consists of a TH400 three-speed automatic transmission and a 8.5-inch 10-bolt rear end from a S-10. Listen as the turbo 4200 is put on the dyno or rear how the project was created in the build thread.
