If you had only used scotchbrite, it'd usually be a no brainer (but it might not have gotten the rust off). But with 'real' abrasives, it's less the case. I'll also note that in the second (cleaned up) pic - it looks like there's a score/groove across each of the two lobes toward the bottom of the pic. I can't say for sure as it might just be the lighting/digital pics making it look like something but in reality it isn't a groove, just a colouration or something (I remember trying to take pics of cams for another forum and it was just about impossible to show what was easy to see with the cam right in front of you).... So i'd be a bit reluctant. Then again, if it owes you nothing, you could always try it.

I would _definitely_ add my name to the list of people (on any forum) who recommend Clive Cams. I couldn't tell you just how good their reputation is, and they earned it fair and square. A few years (actually probably closer to 10-12) ago there was a big issue with lifters from the US that had been ground flat instead of the usual very slight convex shape on the foot. They were lunching cams left right and centre. Some other places didn't check em, and customers cam's were destroyed within a few hours of running. And some of these other cam places wouldn't do anything honourable with regard to replacement. Clive Cams checked their stuff, and their customers (afaik) didn't suffer the same fate. I think at one stage Clive was even contacted about a big job from one of the manufacturers, looking at getting all the remaining lifters that were 'wrong' and machining the proper shape onto them so as they didn't all have to simply be binned. I don't know if they went ahead with that or not.

Anyhoo, when other companies were shafting customers, CLive Cams did rigght by theirs, and ironically (or not) were actually a lot less expensive than the purchase price for cams from some of the other mobs to start with!

I've sort of paraphrased the above to try and condense it, but anyone who happened to be on the moparmarket forums circa 2002 (approximately) would know just how big of a thing this lifter problem was, and just how bad one cam firm (in particular) was in terms of their customer service, production values, quality control and general integrity.

Short version, either try it, or take it to Clive Cams and get their input on it, and if need be, look to them for a regrind if you want to go to a different cam spec and this cam can't be used as is.
