I'll add a little info re: the whole "Match gasser/gassers on fuel" thing. There was a couple match gasser circuits running in the very late sixties, as what we think of as the gasser wars drew to a close. The reason for this wasn't any "bad-ass, run what ya brung, rebel rat-rodder without a clue " bs, it was a simple matter of economics. Match racing is not about some macho gun slinger "Ima callin' you out " bs, thats for the spectators. Match racing is a booked in show where the participants are paid appearance money, as well as round money, because the spectators will come out to see the cars in question. In the early/mid sixties, blown gassers (on gas) had been the main match racing draw. Starting around '66, the funny cars started to transition over to blowers. As they were running nitro, they were now louder, faster, and hairier than the blown gassers, and match-race bookings for the gassers started to dry up overnight. The unwashed masses didnt want to see blown gassers anymore, they wanted FUNNY CARS! Some of the guys that had formerly been getting bookings as blown gassers started to run nitro so they could get match race bookings against funny cars. This naturally led to booked in circuits of nitro- burning "gassers". The main deal that is reasonably well documented was So-Cal based, circa 1969/70, some of the participants were Tom Prock, "the Bushwacker" dart, Kajajian and Lemons blown BB chevy T-Bird, and Gary Burgins former AA/SR, now sans fenders and headlights. They ran nitro, not alcohol, people wouldn't pay money to watch gasser type cars on alky, when they could watch funnycars cackling on a load. Fact is, even with a load, the former "gassers" were heavier than the full-on flip-top ladder chassis funnycars that dominated the scene in '69, and by the same token, people werent really interested in watching psuedo gassers on nitro, they wanted FUNNYCARS! These circuits were short-lived abberrations on the drag racing scene, a mere blip on the historic radar.
