Yes I'd agree with that David. I don't think Grady took his racing too seriously, and probably didn't care about being NZ champion. The car was built for Spinner Black, who didn't have a lot of time for racing, with his numerous business dealings, so perhaps he just thought he'd run it at a few big (non championship) events each year, where it was OK to have the larger engine.
