Wonder if it was the Mobil Economy Run?
I recall:
* closed course
* very slow acceleration
* low average speeds
* bald tires
* 200-psi inflation pressure
* thermally-insulated engines
* no water pumps
* no pressurized cooling system ( no radiator cap )
* entire plexiglass bubbles enclosing the windshield and hood
* zero toe-in in steering tires
* zero camber
* soft valve springs
* Single piston ring
* one-barrel carb
* remove accelerator pump from carburetor.
* no choke
* maximum timing advance
* no air cleaner
* free-wheeling clutches at drive axle
* 'momentum driving ' ( burn and coast )
* low-viscosity engine oil
* low-viscosity transmission oil
* low-viscosity rear axle lube
* zero brake-shoe drag
* high-gear acceleration
* chain-drive
