Let's none of us confuse Performance Engineering with Performance Associates... a long-respected and Ford related company started by Les Richie, then run by his son, Randy right next to the Pomona Raceway. Sadly, they have closed. For those that don't know who Les was, just look up Les Richie.
One of the lucky ones to receive the factory Ford 427 lightweight Galaxie drag cars straight from Ford.
