It was not a MOPAR but my stepbrother and I built a chassis out of scrap cars in the 70's, installed a 350 chevy and a wooden box to sit in. Never took it to the drag strip, but we did take it to an a banded air field and run it. I almost fell out of the box the first time running it, as it went straight up and almost over. Wheelie bars were next. THE GOOD OLD DAYS!!!!! OBTW, the throttle was a rope.
