1971 is a bit beyond this discussion, but I will add that John McCormack did become the fastest Repco 2.5 V8-powered driver around Warwick Farm some time in the period.

The Brabham was purchased for Niel Allen to drive, but by default it fell into Gibson's hands as Niel had other things to do and found it a bit of a dud. I think he drove it just once.

It was interesting to read in the article how Lotus had trouble finding suitable Climax FPF 2.5L engines for this car.

Remember that the F1 for which this engine was designed finished at the end of 1960. So many of the remaining engines had cracked blocks.

In any case other engines such as FVA were being used in the Tasman Series and the development of the Repco 2.5L V8 meant most Aussies switched to that. Also in sports cars such as Lotus 19 and Cooper Monaco the Americans stared replacing this engine with small V8's.

So the engine died out of use. Then Historic Racing came along and quickly there was a new demand for the engine. So various firms in UK started making parts and complete engines.....
Repco bought the rights to build the engines in period, circa 1964. They cast their own blocks etc long before Crosswaithe and Gardner ever got into the game. Sadly, the patterns were discarded in the Repco shakeup of the seventies.
