PLUM CRAZY

A 1929 PLYMOUTH HOT ROD BUILT WITH DIESEL POWER

The vehicle of choice for most Diesel World readers is a pickup with a really powerful diesel engine. And that was initially the plan for a client (who prefers to remain nameless) of ACR’S Andrew Faris. On the other hand, Faris’s client has three kids and likes his Sunday drives. So a four-door sedan made more sense from a comfort standpoint—but he couldn’t let go of his diesel obsession. Why not build on the best of both worlds, a stylish street rod with a 1,200hp Cummins?

At the front, the drop axle rides on Posies springs and a Pinto box actuates the steering
