Erson Cams Quality Discussion

Used an RV cam from Erson, years ago when I had the 1984 Dodge ramcharger, good cam. There was a 'flat' spot whenever we towed a 5000 lb trailer up hill. Once we were past that spot however, she did great. And it wasn't the carburetor, trust me, it did the same thing no matter what we used, either the Holley, Carter TQ, or the AFB.

However this was an Erson cam from the 90's I'm sure you guys have different grinds since then.
