Finnegan' Garage: Cummins-Powered Chevy Dually to Single Wheel Axle Swap!
This '73 Chevy C30 Ramp Truck has led a hard life. It was converted to Ramp Truck status early on and has been hauling cars ever since. Last year we ditched the 454ci V8 gas engine and TH400 three-speed trans in favor of a compound-turbocharged Cummins 5.9L 12Valve diesel and 47RH four-speed with lockup converter transmission. Both the engine and transmission were modified by Powerdriven Diesel for towing duty and hot rod fun. It didn't take long to destroy the stock Dana 70 rear axle. A couple of burnouts was really all that was required to send the spider gears in the differential crying to their mama. Determined the make lemonade out of this lemon, we contacted the folks at Quick Performance for an upgrade.
