Anybody running the '68 4 speed 340 cam?

The product is not available. There is something close, but thats not the same.
It may be good enough for some, but others were interested in the original - surviving examples of which is hard enough.

It's like saying a Tisas 1911A1 is the same as an US purchased Colt or Rem Rand. its close and reasonably priced, but its not the same.

It's tough to measure whether any of them are correct, because Chrysler was so proprietary with their measurements. We all know MP used the .850 for figuring duration at .050", instead of the industry standard of .750. But almost without fail, when you use that .850 to verify, it still doesn't math out. Same with their stock cams. The only real way to figure it is to map it on a cam machine or degree wheel.
