Tom Wells Tom that's a bull story with the Canton guys. We have 2 different motors, My FE motor has longer side skirts than your 460. My
oil returns from the heads are smaller. The ONLY time I everyheard a company tech say to run a motor underfull was 1/4 mile racing. Canton, Moroso, Aviaid, and Millidon all say this is OK. They are not paying for your motor to get rebuilt. Think about this, If this was OK, everyone running autocross and roadracing would be running 5 quarts of
oil instead of 7-13 quarts. As far as the distributor driving the
oil pump, there are 2 thing to take into account, first is having the right gear combo between the 2 gears. This depends on what material the cam gear is made out of and matching it to the correct distributor gear. I have seen many times over the wrong matchups. Harden shafts to drive the oil pumps are very important, IMO. The other thing is having a steady flow of oil going on the contact point between where the 2 gears meet. This is a machine shop extra. Knowing how much oil to spray in this area. 8 years of racing and my gear was just fine. I am running the composite gear to see how well this works out. Tom, it's the little things that help and save a motor to run along time. Will a HVHP pump put more stress on the gears, YES. But if you know what to do to slow down or stop this problem, the issue becomes mute. I would have to look at an oiling system in your motor. I am sure there is a way to lube this contact point all the time.
