I have a 454 Hi Perf block with a 4.25 crank. My distributor gear on my accel distributor wore down over time, and then crushed on the cam gear under hard acceleration at 500 miles. I am running a high volume oil pump at about 70-80 psi cold. The engine was dynoed at 570 HP at the flywheel. Any ideas on why this happened to a non adjustable installation. I know that with a billet cam you should use a bronze gear, but this Crower cam was not a billet unit. What now, tear down, clean out, machine as neccesary and re-build? Any idea why this happened.
