I came across a 1963 motorsport film on Youtube. At one point it shows a Vincent powered hillclimb car. The difference is that it is front engined and FWD. The motor is back-to-front. The question that occurs to me is this: is the drive rotation reversed between the gearbox ant the final drive, or did the engine run in reverse (tricky but I guess do-able). Or maybe a pair of idler gears replaced the primary chain. The car is at 4 min 35 sec. Has anyone else come across this one?
