360 mopar oiling

Whats the trick to keep #6 rod bearing from spinning in my stocker?
Have lost it on the first engine, stock block & crank.
Just lost it in a Race block & different crank.

Have built several Small block MoPars for bracket racing, no bearing issues.

Tell me what I'm doing wrong.

RPM? Any oil system mods, yet?

Std pressure pump.
Feed to the rocker shafts restricted.
Maintains 65PSI @ idle, 70PSI @ 7100RPM

Since you have to use a stock pan, my guess, running out of oil in the sump. Are you using the center sump pan? If so use the Magnum rear sump pan, it will fit the 360 engine. Run more oil, keep it from foaming, air compresses, oil doesn't. Run thin oil, to heavy an oil can't get back to the pan quick enough. Just my opinions...

Had a Dakota pan on my Volare 360 and had no issues so agree that if using the center sump pan you’re probably running it out of oil, especially if you’re taking out oil for ET...probably turning it higher than bracket motors, what is it turning in the traps?

How much clearance? What's the crank journal diameter?

Had that happen to me, on a bracket engine,we did some mods to oil passages, and cut the oil off to the lifters.

Using a Dakota rear sump pan.
5 quarts of oil with big oil filter.

If you are using the newer R block that has the lifter valley closed off, you need to provide more drain back to the pan. Also check the oil filter mounting boss. That area is different than the stock blocks and you will need to add an extra cork gasket between the plate or adapter and the block. If you are running the filter plate, make sure it has 6 or 8 holes and not 4 as some plates do.
