Duane, you got me on the oil pump drag direction! My high school engineering degree failed me when I took a second look at the cut and direction of the teeth: drive side against a resitance (oil pump) will force cam forward. Now the way the cam is retained onto the thrust plate still does not negate a torrington bearing in any manner. The cam cannot go forward due to thrust plate. The cam cannot go backwards due to cam gear on opposite side of thrust plate (thickness .1xx) with the camshafts relief step setting the initial clearance (.1xx +y) so you have a Delta of y which I'm understanding is the thrust tolerance? The Milodon uses a machined thrust plate dimension and with the addition of the torrington bearing, may not use the stock cam step to set thrust tolerance (?). It has to use a positive pressure on the torrington bearing creating
no thrust variance. The cam has no forward/backward movement from any force that will relieve pressure on the torrington bearing. Interestingly, the Milodon 13600 instructions do not have a cam bolt torque. Is the Milodon machined thrust thickness the same as the Mopar stock piece? Damn, its on the block and I cant measure it! You would think they would have shims available to adjust this spec.
Trying to think how the torrington bearing would chew anything with its 2 hardened races on each side of the rollers unless someone forgot the races?
<<EDIT>> the torrington roller bearing cage has a slight cup to it, maybe that is the only positive force on it if it uses the OEM thrust spec?
