Re: Roller cams, cons.....pros???
Oil is a huge problem right now with flat tappet cams. Shell Rotella is what a lot of pro stock guys and engine builders are reccomending for flat tappet cammed engines. All of the additives that help prolong the life of the flat tappets has been done away with in most off the shelf oils. All has to do with EPA stuff. Thats why a lot of people went to the diesil oils.

So why did my 420's w/ flat tappet cam get 852 hours without any adjustments in 17 years running Quaker State 20W50?
Why would I want to go roller when I do the rebuild?

Do yourself a favor and upgrade to a hyd. roller cam, you may get another 30-50 hp out of it anyway!

There are better cam cores available, lifter's too, but you must find someone that can get them for you.
As far as the oil................it is the truth. You just have to believe us on that one !!!
Two decent threads - I have more if you want, but you'll get the idea. Oh, don't mind that CFM guy, he's a pain in the azz.

If you believe that some/most of the lifter/cam issues are related to wear at idle due to poor oiling...check out the KE spray bar solution
