Ray,
I still think it was amazing that from the mid sixties when F1 had 3 liter engines and the Tasman limit was at 2.5 liter we had all the teams such as Lotus, Brabham, BRM, Ferrari etc build special engines to come out and compete and that is where I give Mr. Frost and Mr. Sykes a lot of credit. It meant that in the right conditions the local drivers such as Kerry Grant, Roly Levis, Frank Gardner, Frank Matich could race right up there with the "big boys". and at less than a 1.25 mile circuit, racing at Levin was was wonderful entertainment apparently.
