Done all that before, more than once, plastigage included, under the car. Replaced main bearings too. No I do not love punishing myself like that \:\)

At this point I am not concerned about measuring anything since I will have the damn thing machined to an exact size. I'll measure when it comes back from the machine shop, just to make sure they didn't screw up.

I may end up pulling the engine and putting it on a stand, that was my plan anyways. I just wanted to know if the crank had room to come out without separating the engine from the trans. I guess it's a matter of how deep it engages with the torque converter and how far back the TC can be pushed once unbolted.
I can see a challenge in supporting the crank evenly when removing the caps, as well as putting it back in \:D
Don't need a banana for a crank.
I was just curious.
