Erson solid roller race cam from my small block chevy. The valve lift is .675 on the intake and .645 on the exhaust. 108 centerline with 4 degrees of advance. This is a very low mileage cam. May have 800 miles on it. It is a very good sounding cam and makes killer power up to 8000rpm's. I'm changing cams and going with a different setup. The numbers on the end of the cam are as follow. Erson R286-450 & R298-430, the part #6395. In perfect condition with no signs of wear. No wear to lobes or cam gear. I'm not sure on the duration but you could call Erson's tech-line for the rest of the details. First $200 takes it. Only reason for selling it is I'm going with a little bit smaller cam and a cam that's more of a nitrous grind.

 

duration?

 

I'm pretty sure it's a 286/298, you can call Erson's tech line to find out for sure if you want
