Only know what I have read.....it says not to use with used camshaft...
We now offer fully machined, specially coated and processed melonized steel distributor gears for both small block & big block engines. These gears are designed to be used on steel roller tappet camshafts that previously required a bronze gear on the intermediate shaft. The problem with the bronze gear is that it wears very rapidly, especially on the street and therfore requires frequent replacement. These specially coated gears live with O.E.M. style lifespans. But wait, that's not all! They can also be used with stock or aftermarket cams as well! Hey, these babies work on everything. Only one caution, Do not install them on a used cam. - Call us first!
High volume, or high pressure oil pumps are not recommended as they accelerate wear on the cam gear and oil pump drive gear
