    You can see the lifter collapsing while the engine is cranking over.

    You think that lifter is stopping it from starting?

    Good cranking speed to start.

    What would removing the torque converter change?

    Hell , you have taken the heads off and the cranking speed has not improved at all . Eliminate the converter as a cause of the slow cranking .

    Yup isolate/confirm the engine as your problem

    I would have bet my lunch money on the distributor being 180 out but it doesn’t explain the slow crank. Something must be binding.. or a weak ground but I am not a mechanic just an uneducated guess

    Good luck

    I sanded down where the starter mounts up. Still not pumping hard enough. I can't imagine what would be slowing a crank down that much.

    General engine component resistance. Good job so far, wish I got that much done daily!!

    Did you mention if it had any oil pressure?

    No way to check.

    Spin the pump drive with a drill. If there is any pressure you'll see it come out of the lifter galleys and passage in the block to the head. No OP means tight bearings and possibly the cause of the original failure.

    And I do that where the distributor would seat in the block?

    Pull the distributor and look down the hole. You will see the pump gear rod coming up at you with a slot in it. Find something to turn that rod and you will turn the pump gear and make oil pressure. If you look at the bottom of the distributor you will see there is a pin there. It is what turns the pump gears during engine operation. There are tools but also all kinds of hacks from screwdrivers in drills to welding a pin into a socket and using a drill. Just make sure nothing can come apart and fall into the timing cover or it will become a bigger job again
