distributor aux shaft trouble
Hey guys. In the last 4 weeks I've torn up 2 aux shafts and 2 distributor gears. They were even in 2 differnt blocks the only thing in common was I used the same head and both were ford 2300s we turn to 8000 rpms. I did not shear the pin on the distributors and it was that little stock pin. It just ate the teeth right off the shaft and distributor gear. The first one to tear up had a high volume oil pump (I figured this was the problem) with 70 psi of oil pressure cold. The second one to tear up had a m86c oil pump shimmed .125 thousandths with 65 psi oil pressure cold. Am I running too much oil pressure I've heard tht will do it. But I thought that would shear a pin more likely. Any information y'all have is greatly appreciated. I'm pretty new to mini stocks this is my second year. Is there anything other than oil pressure I should be looking for?
