I think the A/FX Mustang they're talking about is an ex-Dyno Don Nicholson 1965 427 SOHC Cammer that had been raced by Len Richter, then Jerry Harvey and Hubert Platt, then sold to Nicholson. There's a very interesting story about it's "rediscovery" in a real bad neighborhood in Brooklyn in a recent book called "The Hemi in the Barn" by Tom Cotter. Apparently, the last time Nicholson drove the car he was at Englishtown, NJ where "he popped the clutch at 9,000 rpms and made it through the traps at 9.89 seconds, setting a new NHRA track record and winning the class for the season." By the time he made it back to the paddock after the run there were already a group of men with bags of money ready to buy the car. Apparently the guy was a famous street racer (and numbers runner/drug dealer) Tab Talmadge. I've attached an image of the Mustang. So no it wasn't owned by Heavy, but an interesting story none-the-less
