On the other hand, my idea only includes grinding. Yours obviously would provide larger FE gains, mine would be cheaper although I don't have any idea how much cheaper.
Thanks for the info on the magazine articles Christ. I assume I can get those online somehow? I checked Hot Rod's website, but I couldn't find where I could get old articles.

We've been regrinding cams since 1970 here at Kams, Inc. in Oklahoma City. Welding a cam lobe requires different procedures and materials depending on the material the lobe is made from. Some cam designs are also difficult to weld. However, it can be done with the proper techniques. A properly welded and ground cam should last as well as the original did.
