Small Block Mopar Thrust Bearing issue

[Adger Smith]

Mike,
The drilling for positive oil is a good idea. I use a less labor intensive way to oil the thrust.
Take the top(block side) main bearing and use a file to make a small angle cut right at the parting line. You do it only on the back side of the bearing on the thrust side. I usually do both sides of the bearing. You slot it on the portion that the crank journal runs on so the oil goes into the cavity that makes the roll into the thrust face. I don't slot the thrust face. Take a little scotch brite and smooth the edge it rolls up on the bearing. It doesn't take much of a slot/angle to provide positive oil feed from the main bearing feed to the thrust. Get the converter fixed.

Adger, Thanks for the info on the thrust bearing modification. I like the less aggressive way you suggested. Is it possible for you to send an illustration to me? My e-mail address is mc340dart1@aol.com. Thanks again,
Mike
