Bottom of lifter worn thru

We are all doomed when the zombies come

The roller vs flat tappet is almost like the iron heads vs aluminum debate. There will never be a consensus. I will say that the magnum stroker I have was nice to fire up and not have to worry about break in. I have nightmares about this 440, but really it isn't anything that hasn't been done a million times before without issue. We just get to read about the problems because people don't come to forums to brag about how well their cam swap went, they come her looking for info on why everything went to hell. like a worn through lifter. When the oil companies took the zinc out people were wiping lobes left and right and blaming it on the manufacturer and giving them a terrible rep that some still have to recovered from and others completely changed their warranties to cover their bums from us!
