Actually, I just want to confirm, I had a "long block" built from scratch -- while my engine was still being pulled out of my G. The finally assembly of the long block was held up until the oil sump and, especially, the flywheel could be shipped to the facility (so that the flywheel and crankshaft (and all the other parts) could be balanced as a whole unit).

Frankly, I'm not sure I'm familiar with every one of these components, but the brochure reads that their SHORT blocks are prepared with NEW:
pistons, oil pump, timing chain & its guides, rod bushings, crank seals and spacers, freeze plugs & seals, block side covers, oil pump bushings.
...with "replaced as needed":
Timing gears, flywheel ring gear.
...machined to exact factory specs:
bore and hone surfacing, align home (if necessary), connecting rods, reground crankshaft.

And then, for LONG blocks, add (in addition to all short block features):
cylinder head completely machined (pressure test, resurface, cut seats, new guides (honed).
Plus NEW:
Valves & guides, valve springs and rocker arms, new camshafts (of course, mine were special ordered), new chain tensioner.
Replace as needed: cam bearings, valve train hardware.

Whew. That's about it.
