Calvin Nelson and his 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.

Sadly, the vortec4200.com forum died without any avenue for someone else to take over.
That is terrible. Maybe this is a viable alternative https://www.facebook.com/groups/1964263467156690/
Always liked these 4.2 engines and I’m digging how it’s like the new engine to swap into things. Kinda breaks out if the “LS swap everything” norm
