360 mopar oiling issue

[CMcAllister]

I blocked oil to the left galley at the #1 main bore. Bushed all the lifter bores. Oil to all of the cam bearings was restricted way down.

Oil for the heads (stock OE LA style oiling through the deck) was taken off of the 2 and 4 cam bearings and provided by plumbing under the intake. It was also restricted. Rocker gear wear showed a slight increase in wear, but I was running a fairly mild roller with not a ton of spring pressure and Crane Gold rockers.

Port matched the pump and the rear cap. Massaged and enlarged every galley in the back of the block. Put a big pump in and used dual pickups.

An external line was used for simplicity. Not allowed on a legal engine, but as I read the rules, plumbing under the intake would be OK for SS. Not sure about Stock since it's not "external" but it's also not "as produced".

In the end, the only thing getting oil from the main RS galley was the crank and 4 small jets for the cam bearings. The top end was plumbed separate from the crank and was controlled.

I blew up one engine and had to check the filter every few runs, and replace rod inserts on one or two rods every 6 or 7 runs to keep from blowing up #2. After putzing around with pans, big oil pumps, crossdrilled crank, 3/4 grooved bearings, with no help, I just took it apart and completely re-did the oil system. Went to staying together all season, filter looked pretty good all season, and not looking too bad at the winter freshen. Just had to watch the rocker gear and pushrods.

Plenty of other folks are running these things over 7k with OE cranks and they may be doing something different. Some are installing the cam bearings to cover all the holes and redrilling them whatever size they think is correct. I used drilled plugs that could be changed easily if needed. My stock crank 340s were never this fussy at 7800, until I cut an iron 360 crank to go into a 340 block to get some cheap stroke. Something about the 360s and that iron crank.
