Flat tappet ,still decent.The devil,in the details.On my Chev rat,popped for the Crower" Pro 55" billet ,for a solid flat tappet. The lifters went flat,cam lobe looks new.Watch the little details.
Exactly. I have had good luck with flat tappet cams, just gotta make sure the lifters rotate in the bores correctly and it fires right up. I've only had 1 cam go flat on me when I did everything right and guess what brand it was?
