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.

I don’t know if dad had much to do with it... I honestly don’t know... I’d have to ask Bob.
Bob could have very well been working on it on his own at KBRE. It’s kind of a blank history for me after the Rossi NASCAR and with my dad retiring in mid 72... there was always something he was doing, be it the Hemi as well as a very successful slant six for hydroplane Racing, also SK boat racing using the 426 Hemi’s. Again I was very young and much into the nitro funny car thing with so many of them on KB’s premises at the time.
The 305 used Kinsler injection for the F5000 per Bob’s book is all I know. Sorry I can’t give a more definitive answer for you.
