The Plymouth Weslake DOHC Motor from the 60's

Did your dad also help Bob Torozzi and Bruce Junor with the 1971 Questor Grand Prix motor. It was a special race at Ontario Speedway that put American Formula 5000 cars/drivers versus European F1 car/drivers

Swede Savage drove a Formula 5000 with a 305 Mopar motor, AAR Eagle chassis. He wrecked badly in practice with a stuck throttle. In hospital for days but survived. It bothered Bruce Junor and one of the reasons he left AAR.

Heard Tarozzi say once it had a trick injection system. It didn’t have Westlake heads. I don’t think those were legal in F5000.
