I just installed my new comp cam in my 90 GT with 114K on it. The comp directions say to always install a new distributor gear. Is this absolutley necessary? Do you guys always use a new one when installing a new cam? Thanks!

Well it depends, there are two types of camshafts non roller and roller

Non roller camshafts are made out of cast, so they are pretty soft.

Roller camshafts are made out of steel, hence the need for a steel and not a cast distributor gear, if you put a non steel gear and use a roller camshaft the gear will get chewed up in a hurry.

I had the same problem and thats exactly what comp cams told me.

already covered that. It is a stock 90" 5.0 roller motor and got a comp roller cam, but the instructions that came with the cam stressed to always use a new gear. I had never herd of this with a roller cam and wanted to make sure i didn't have to change it. I'll probably just run the stocker and keep an eye on it for the first few hundred miles.
