I can't say enough good about Delta Cams in Tacoma Washington. I have been buying cams from them for forty years. I have bought regrinds for stock engines, modified and full out race engines. Recently I gave up on the noisey hydraulics in my 235 and had them grind a hotter version of the solid lifter truck cam. Couldn't be happier.
