Ron,

Ive talked to Dwayne at length about this on a couple occasions.

He says the -5 Comp lobes are very very reliable in a real street driven application.







And Dwayne is right.
I got my -5 grind from PRH and it has been very good.

The first design street rollers are nice grinds too, though, and worth checking out if a guy wants to buy a shelf grind.

I was going to go with the older 308 street roller until Dwayne picked out a -5 for me instead. At the time our feeling was the -5 would pick up some power without hurting reliability/longevity enough to notice.





Zippy can I ask you the cam specs on that cam and the spring pressure you run with it ??? Thanks , Ron
