Air date: Apr 02, 2023

Mike Finnegan’s Garage we finally Dyno-test my Cummins 12 Valve diesel-swapped Chevy Square Body ramp truck. The guys from Power Driven Diesel are back to upgrade the compound turbo system and swap my stock head for a ported unit. We also installed a better set of injectors and a custom p-pump. We did the work in one day inside of my garage and then drove 20 minutes to Mo’s Speed Shop in Dallas, Georgia to find out how much power the truck makes.
