A couple of the popular American vendors offer "new" cams that are stated to be like the European spec cam. One is described as a regrind, the other says it is from a new billet. Both have undersized base circles (I don't understand why a new cam made from a new billet would be made that way). Unfortunately one of those does not offer much information on its specifications, but the other one has a nice spec sheet (below). From what little data I could get on the one with limited info, it appears to be rather different from the other one (with the full spec sheet). It would be interesting to be able to see more about the limited one so a better comparison can be made; unfortunately that vendor does not have further info to offer. Also I'd like to see a spec sheet for the stock Euro cam to compare the others with it, as neither appear to be exact clones. I'm sure there must be full specs available somewhere for the Euro cam? Although it will likely be in the rather useless format that does not comply with the industry standard (e.g. lift at .05"). I wonder if anyone has actually profiled the stock Euro spec cam? SteveC was working on doing this for several performance cams but I don't think he has done it for the stock one(?).
The spec sheet for the MWB D-223 (#B21A) cam (listed at the more helpful .05" lift):
