Mopar has no prevision for push rod oiling

They look like Very old Comp lifters.
I have not had a roller cam AMC in many years but the two lifters I used were Comp and Crane .
Lots of choices now that .904 lifters are available with pushrod oiling and in many different oil band locations , but I would only use them if not bushing the lifters.
I used to bush the bores with the oil feed hole located to match the oil band of a small block Chevy lifter with a .842 body and a .750 wheel due to the small base circle on the cam i was using and also used Ford tie bars.
Now that Jesel and T&D have high ratio rockers I would bush the bores to decrease oil loss and go with a conventional base circle,. But still use the SBC bore lifter to maintain an optimum oil gally diameter

I have a couple of sets of older Comp AMC lifters here from my bracket car and they have non separable tie bars. Even though Comp didn't say you had to, I had to bush the lifter bores as the slot for the roller was into the oil gallery at full lift.

Thanks all.
It's probably a moot point on who made them. They are brand new. Just need to mock it up to make sure the body groove doesn't uncover the lifter oil galley passage for a pressure loss at lift.

Tom, I have one block that is sleeved and set up for chebby lifters and
ford tie bars like you did.

Looking to see what else I need to build two motors with the parts I have on hand. One will be a street/strip with ported iron heads and a 4 speed. The other is a Fred Brewer headed 427 AMC, sheet metal intake with Turbo 400.

Thanks again,
