Is there anyway that the now extinct Revolver Cam grind for Evo VIII's can be duplicated or reproduced? Maybe this is a dumb question but I just wonder?

So, Mike, I guess that I would first need to find a set of original Revolvers and then take them to a shop that grinds cams to order.
I wonder if the Revolver profile was a regrind of the stock factory cams, or whether blank billets would be needed to duplicate the profile?

They still pop up every once in a while. That's how I got mine, waited until a set was for sale on the forum and did what I needed to do get them. Only negative is that the intake cam was off a lot and bent my new valves on cyl. 4 even further halting my 3+ years without it running.

If you can them for a reasonable price, I say go for it. I got them as they would be great for my 2.3L and IX turbo (old Green in the shop for later) but I don't plan on using them forever. I have a S2 intake cam to mix it up later on as well.

The original Revolver cams were not w/o issues. There were several cases of extreme variances in production quality control. Some buyers couldn't get the things to run right as produced, or achieve the advertised power numbers. I don't much like buying used cams myself.

I FINALLY pieced together my engine with the 2nd set of Revolvers I had and now I'm EXTREMELY worried about starting this thing up....?!?!?!?

And Sparky, the Revolovers are not regrinds off the stock cams. They look completely different when side by side.
