With a 4-5/8 crank 7200 was the big number & we could make multiple passes without even pulling the heads. One meet we made eleven passes then changed the engine on Thursday for a class change to the B engine. It liked to put all the oil in the top of the engine & out the vent hoses onto the chutes so it was a little hard on bearings until I built what became known as the Sidburger oil pan design then the back of the car was always as dry as a popcorn fart as somebody phrased it.
