I bought this Comp cam off eBay and it was listed as never used. The box was sealed but what surprises me is the etched grind numbers rather than stamped numbers. This is the first Comp cam I bought. What do you guys think?

From the Jegs catalog:

Xtreme Energy 294H Hydraulic Flat Tappet Camshaft Complete Kit
Lift: .519/.523''
Duration: 294/306°
RPM Range: 2800-7000

You should call Comp Cams to make sure this is correct. It should sound very good.

Most Cam companies stamp or etch, it's common to see either from the same company.
