318 or 360? That is my question...

thank you, that's what I've been reading. It's an auto. The bottom end seems to be fine now no noise/issues with the bearings. Is there anything special I should know about Mopar lifters?

Not really. There are two types that you should be aware of. The LA engines that have a rocker shaft do not have an oil hole in the lifter, and hollow pushrods. The Magnum engines have the oil hole in the lifter that, with the hollow pushrods, provide oiling to the pedestal mounted rockers. The early LA can use the Magnum lifter, but not the other way around.

FWIW: The Magnum lifter is interchangeable with the late AMC V-8s.

Curious about what happened to quiet the bottom end. Usually when a bottom end makes noise it's because it's terminally ill. When it goes silent, it's because it has arrived at the terminal.
