Roller is better, but you can still use a flat tappet cam and lifters if you take a few precautions. A lot of the failures have been attributed to improper cam break-in and using a cam with aggressive lobes and springs with a lot of tension. My 383 was built in 2000 with a flat tappet cam, but had I known what they were going to do with oil, I would have opted for a roller but at the time I could not justify the added expense. I use Rotella T oil and add a little zinc additive just to be safe.Last edited by rumrumm; 04-11-2016 at 07:42 AM.
