Crankgear positioning

Good deal on your cam being installed straight up, that is all you need to know at this point to get it running right.

If you have your engine opened up far enough check the lifter bottom on the lifter from the short - .014 ths cam lobe and see if it is starting to dish out.

Heck, check all the lifter bottoms for dishing they shoud all be flat. Keep the lifters in order to their respective cam lobes also if you plan to use them again.

Did not tell us if it has hydraulic or solid lifters ? Do you have the adjustable rocker arms or the factory mopar bolt on rocker arms ?

The camshaft could be going flat, high lift, high pressure valve springs, and using today's regular engine oil with out the zinc additive in it can all lead to cam failure.

Can also easily cut the can off your oil filter and see if there is any steel floating around there in the bottom. Can take a magnet to the paper filter too, if there is any steel in it it will jump to the magnet.
