If you have a used cam that is not totally worn out, have it reground. I like Schneider Cams in San Diego. They can regrind your stock cam to stock specs, or as wild as the core can take, or anything in between. The GM cams were of very good quality metal wise and over the years I have had quite a few reground. In fact I still have a motor I guilt back in the middle 80s with a cam that Chet Herbert reground to .480 280 specs. So there is a pretty good range available for a regrind. New cam blanks are sparse and have been for a while and who knows what the metallurgy looks like. So a regrind may be a very good choice.
