Roller lifters have few and far between failures? I bet they are on par with the FT failures just lack the density in people running them.
These engines were designed to use a FT cam and that is a fact. Sure you can run roller but don't expect it to solve all your problems because it won't. Don't get me wrong though if I saw no roller failures i'd be running them.
What about the DLC coated FT lifters coming out? Could be a game changer.
