The 383 in my 46 was built about 15 years ago with a Comp flat tappet cam. It was broken in right and the oil was changed regularly. I had to tear it down last year and found 2 cam lobes beginning to go bad. That wasn't even the reason for the tear down, but it would have been eventually. It's going back together with a retro fit roller cam. I don't build many engines, but I won't build one without a roller cam from now on. Too much time and money invested to roll the dice on if the cam will hold up.
