Yeah, duh, I forgot about the Terry Prince car that bid to $298K a while back on BaT.
I did a little reading up on Frank Sanders. He won the class at the 63 Winternationals with this car, coincidentally beating Terry Prince in the final. Post-race teardown found that he had an illegal camshaft, so NHRA disqualified him but would not award the win to Prince
They also banned Sanders from all NHRA races in 1964, so he switched to running AHRA.
