On more than one occasion I’ve thought that Cummins swapping my squarebody dually would be the wise choice, rather than putting together a bigger and badder big block for it. I hesitate to move that direction thought because A, Cummins swaps aren’t nearly as “cheap” as people try to claim, and B, I think I can get similar results with a built big block. And then stories like this come out where Finnegan’s truck is making 1,350 lb ft of torque. Jesus help me.
Watch this and learn all about the Cummins swap and big power upgrades that Finnegan has done to the OG Ramp Truck.
Video Description:
In episode 136 of 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.
