If you don't like the Eight you'll hate the V-12.

I wouldn't try the pre-assembled block method without eight ring compressors. The eight standard ring compressors from Lisle will hold the rods high enough to avoid interference. Without the crankcase in the way it's a little faster, but the rod bolts should be removed and sometimes they aren't very cooperative. So I always played it safe used the standard method.

After some thought, I think the piston and rod assemblies will go in from the bottom with the block on the bench. But you still need eight ring compressors to hold the rods up.
Packard sold reconditioned long blocks so this must have been the way they built those motors.
