hughes cam quality?

I believe the cams are ground by engle for the company. Engle has been around forever, and is a reputable company. Todays oils are a real pain in the rear for the performance market. Most if not all the zinc has been removed. Use a break in additive+ use a good quality oil such as Brad Penn or Gibbs if your running a flat tappet style cam. I have all my cams ground on a pro 55 or better core when running the aggressive stuff. But proper breakin proceedure is the key to a long life for any camshaft.
