sorry but even a regrind that had material welded on so that you can get a larger lobe may perform as well as a billet cam but it will *not* last as well specially on high performance use in engines that will never have their cams swapped more than 1 every 2 or so years.

Its the old story of having a stock crank re-welded so that you can have a stroker kit. It will work, but forget about reliability.
