standard or HV oil pump?

[Scufty]

went through the first one after the rebuild...(should have changed it out)
Then a bronze after about 250 miles. Changed to a iron or cast not positive...
and its not too bad after 250 more
thoughts?

I run the above HV mellings pump no problems. Steel gear as per crane's recommendation no problem. MSD distributor hd pump shaft. I don't know why people take recommendations of what gear to run on there distibutor when you should call your cam manufacturer and find out. Good luck.

How about a HV pump but with a stock bypass spring. This way you don't bump the pressure and put a load on the gear, but if you need it, you have the extra volume.

Mine is the recommended cast gear for the cam shaft from the manufacturer, and after 5,000 miles there is no wear on the cam gear or the dist gear. I don't run the HV pump. Even when I had the mechanical roller cam before the rebuild I could have swithed out the bronze MSD dist gear for the steel one from Ford Racing.

A steel gear is good for OEM roller cams but not solid rollers. To date, the only option has been bronze. I was looking for info on the new Comp Cams composite distributor gear and saw another thread on this subject. Supposed to solve the wear problem associated with the bronze gears, but burnishing the cam gear also recommended along with blueprinting mating parts.
