  1. In 1965 Jack Brabham and Australian engineering company Repco took the slightly stronger Oldsmobile version, with an extra head stud per cylinder, and developed it with overhead camshafts and new heads etc into a three litre Formula One engine that won Jack Brabham the Formula One Championship in 1966. Then in 1967 it gave Brabham cars a one two in the formula one championship with Denny Hulme of New Zealand taking the honours. So beating Ferrari and all the other exotic make engines and cars behind the Brabhams. No driver since or in the future look like developing their own car to win a Formula One championship. Brabham also won the Formula Two championship in 1966 but with a little known Honda one litre engine. Jack often winning both the F1 and F2 race on the same day. Not bad for a discarded GM block.
