Since I'll be using stock heads, stock cams, stock intake manifold, stock exhaust manifolds and basically EVERYTHING but the shortblock the same as my old setup, it won't be that much better... maybe as much as 20 HP. However, the built block is the foundation for future mods.

I tried installing a temp engine... it suffered a head gasket failure. Warranteed blocks are like that...

Most factory engines are a rough approximation to the standards you are using. day one on the bore mill is good, day 7 not so good. hence coal. the start of a diamond. get the right engine on the right day, and it seems unnatural, a day later it is a mass of metal called an engine.
all products start as a raw material. your starting block/crank/rods etc are the coal. you are making them into a diamond.
got the drift now?
balancing?

Eh, more like using a fracture testing apparatus capable of delivering EXACTLY xxx impact energy every time to put tacks in the wall for hanging pictures...

Feh...
While the crank was in the lathe to polish the F#@$ing shot peening out of the rear main seal journal, I went ahead and indicated the lathe chuck in and checked the crank for runout. It's less than a thou. I was somewhat concerned because the crank was shipped to me in a cardboard box full of styrofoam peanuts with NO FURTHER PACKING. Grrrr.... Oh well... no harm done except my time for making sure the other guy didn't do something stupid and screw me over.

Haha... a Chevy is coal... The Northstar is a diamond in the rough. It's most of the way there, it just needs a highly skilled artisan with arcane knowledge of deep magic to put on the finishing touches.

I knew this was a Mickey Mouse job all along!!! 
I can't believe you're going through all of this and you're putting a bone stock top end back onto it. You really have lost it, I think the coal dust is getting to you.

Why do you think this build has taken so long? One does not learn deep magic overnight.
Gapped, cleaned and bagged the rings. The pistons and rods are already bagged. I just have to clean the crank and finish cleaning the block... wouldn't you know it's about 1/4" shorter than the inside of the dishwasher?
The "host ring"s for the gapless set actually had negative gap and needed a gap of .026... that's a lot of dam ring filing.
I also had a nice conversation with Kevin at Total Seal about the details of the lapping process and the proper way to orient the host ring and rail to get them to measure out correctly (ie, perfectly).

I should have known! (that thread made my head hurt, I have't done formula work like that since I finished college 31 years ago, and don;t want to anymore)  Again, you really take things to the extreme, but it's your way. I just hope you got it all right, and it performs as designed.
As for the dishwasher, I won't go there, you either are single or have the most understanding wife. I know I had to take a week of cr@p for just heating the rods in the oven with the pins in the freezer and reassembling them on the counter. and that was a long time ago...
I'll go back to watching again, carry on!
