Gotta admit I did see a bloke from Gladstone/Rocky? blitz the flat track events at LCMP one year in a ten y.o. very stock looking triton. The guy could drive - or he had nothing left to live for.....
Not sure how stock the donk was though, but the main factor was that he had very well sorted ifs and drove all over the big boys in the comp utes.
Such a shame, it's probably rusted by now.
