Hello
Im doing this very build right now. I picked up some Howards EDM lifters, to use with my Ray Barton custom Bullet cam.
Anyways
I have heard a bunch of people talk about burning push rods up, and lack of oil to the cups etc. This engine (572) uses all new stuff, the block is a new One from World with a 4.5 bore. CNC ported heads...bla, bla, bla
Seeing how these lifters make it possible for push rod oiling, due to actually being a AMC lifter... I plan to use them in this fashion. Manton Push rods will install a .030 restricter in each push rod for free, to keep oil control down, and bleeding oil to much. The valve train will oil in the normal fashion, but this to me is worth the extra trouble, and wont cost me a dime really if you already have the lifters..
