Okay good news! Settled the engine a little more and got the tranny x member in. Sitting more level with some space on the AC pulley there’s not enough room for factory engine mount on the drivers side, that big one that offsets the factory engine so much. And I was thinking this makes the front driveline interfere with the oil pan or starter etc. it just looked like there wasn’t near enough room for the front u joint or balancer or anything before just rotating the block a few degrees and, it looks like it actually clears pretty well! So we could leave engine here I think, and retain factory AC. I’ll need to check driveline angles etc however. The t case is a lot farther back now so that part needs lengthened in at least one place, but may need length added on both ends.
So so how much room do we need in front of the harmonic balancer? I’m at about 1/8” or less right now. Seems a tad tight.
