My doomed 408 build

Ouch.

FWIW, only cam to ever flatten a lobe on me was Hughes camshaft.

I would never recommend anything made or designed by Dave Hughes.

Best of luck.
Well we all know Hughes is a massive repacker. They don't make their own cams they may send the recommended designs to somebody who makes them but they certainly don't grind them in house. They get somebody like where I go to Oregon cam have them ground and sell them as they're hot ticket for way too much money...
