After the new 1.5 liter formula came into effect in 1961, a Mark II version of the 2,497 cc unit was created, measuring 1,499.8 cc. The 1.5L engine won three Grands Prix that year, until superseded by the new Climax FWMV. Later, the older unit was bored out to 2,751 cc for use at the Indianapolis 500 and for sports car racing. The exiting 2.5L engines gained a new lease on life when the Tasman series and Australian National formula came into existence in 1964, both having a maximum engine size of 2.5L.
