I should have said that the B4 had a 3 speed gearbox, but even so, 90 mph in 2nd gear! Would that have been possible, or was it just an urban myth....the hotrod boys will know. And yes, the heads really were special, they had some sort of finning on them, the only detail I can remember....weren't just old heads with some silver paint sloshed on them. The thing is those old engines did the business with torque rather than revs. When I hear the old Gee Cee Ess 'chuffing' along these days it all sounds very relaxed compared to some of the screamers around it. Too many revs and that old enemy of the race motor, heat, sets in, and there were more steaming kettles on the track than at a Sunday school picnic!! Vintage car man Roy Rowe has a classic flathead V8 midget speedway car which I watched at the recent Roycroft Trophy meeting at Hampton Downs. A beautiful little machine with a wonderful history and really looking the part in it's yellow paint job.. He was telling me of his efforts to keep the thing cool..ish...and the water in the radiator where it belonged, it being a much more efficient item than the original. Indeed he has gone to 'waterless' coolant....very expensive but it works and allows a much higher boiling point. He was also saying that in the flathead V8 the exhaust gasses exit the block in such a way as to heat up the coolant even more than usual....is this right, can't remember the details. There are some pictures of the old GCS with a massive truck-like radiator that George has No8 wired on to the front of the beast in an attempt to keep the temparature down....didn't help the steamlining much. So, 90 mph in 2nd gear with a 3 speed box...yes or no. Has been worrying me for 50 years. I need to know, otherwise my vision of Brydon in the B4 ending up in the ditch will be for nothing.
