Bill "Grumpy" Jenkins died this morning in Pennsylvania. That's all we know at this time. As more info comes in, we'll be sure to post it here.

In his last known interview, Jenkins sat down with long-time friend and automotive journalist Jim McCraw for an interview for Super Chevy's April issue. He's sitting here in a replica of the original "Old Reliable" '61 Chevy, for which he built and dyno tested the engine. The car features some of the original parts from the real car, which has never been found.
