    But is the torque converter still bolted to the flexplate ???

    The valve that's barely opening is #6 intake.

    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 .

    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.
