The Crane retrofit hyd / roller cams are a steel billet cam with a cast gear so you can use your stock type pump drive and gear. I don't know if the Comp retrofit cams are the same design. Apart from that there is a 'Sardi' [sp] billet that is tough enough for a roller applications and you can also use your stock type pump drive gear on it. This is what most of the custom grinders use for hydraulic roller grinds.

I have been running my Comp Cams Retrofit Thumper Roller Cam with the stock distributor gear. Got a bit of a run around about it though. One person said I did, but through Summit Racing, it showed that if the part number ended with a certain number,which it does, it wouldn't be necessary. I called Comp Cams back up, the next person I talked to said to use the stock gear. We will see.
