Solid roller cams HV oil pumps?

Yeah. I can clearly see your point. I tried getting through to Comp Cams recently on the phone. Was not successful. Waited on the que next one up then bumped 9 before me. Called later no success. Gave up. Could have emailed questions I suppose.
As stated it's nice to get a knowledgeable person on the phone. That service seems to come from the smaller businesses.
