Engle HEV 3945AS Camshaft

I saw a post somewhere online that Hughes sold some Engle grinds. Maybe they can give you some info?
Engle ground hughes cams to his specs, he won’t know about engles propriety cams. He told me he would not grind me a Hughes cam as it was Hughes propriety grind. engles cams were half the price of hughes cams. This was about 20 years ago.
