Some might wonder why Tim isn't involved with the re-assembly of this engine. First, I would love to have Tim involved, but he is 600 miles away now as I have moved to Oregon. Remember, I'm trying to remedy the problem I encountered with the engine being so terribly difficult to rotate after I relieved the cylinders with the pistons still installed. There may have been other issues, like solidified assembly lube as this engine sat for quite a few years, but no matter, this is going to be a great engine.
I have been doing most all of the assembly work myself with the guidance and sharing of special machinery from a local engine builder. He is also a race car owner and driver on the circle track courses. While there are a stream of flatheads going out of his shop, MELs, FEs, and a few Y-Blocks find their way here too. However, he is not a Ford owner of anything and we poke fun at each other all day long. Did I mention I was having fun with this engine?

.....His balancing of the rotating assembly is second to none (sorry Ted).No apology necessary. Tim does good work and that’s alone speaks for itself.

The crankshaft is in and the main caps are set in place. The center main with the thrust bearing is torqued to spec first. This allows the end play to be checked and if it is not in spec, unbolting and slightlly moving the cap before torquing it again will change the end play and perhaps enough to get into spec.

All mains torqued to spec. Rear main seal is installed with silicone sealer everywhere, but sparingly. Seal is rotated in the block and the cap to expose 3/8" of seal on one side leaving a 3/8" cavity on the other. This gives a solid seal at the block and cap parting line. Oh, yes, place the lip towards the oil.

Rods are next, but first a small machining process to correct my mistake.
If you should decide to stamp the rods and caps to mate up correctly in the future, make sure you do so while they are still attached to the crank. If you stamp these off the crank a distortion may occur.
When this short block left Tim's shop, I know the big ends of the rods were well within spec. However, when I decided last year to take the engine apart, I couldn't read the finely engraved numbers to match up the rod with the caps. I wanted to make sure I could easily read them, so I stamped them (off the crank) with a 3 pound hammer, I'm exaggerating, it was only a 2 pound hammer (my dumb a**). They were not far off, but out of spec is out of spec.
Checking for out of roundness.
Material was removed from the mating surface of the big ends and then the rods were honed to the proper size.

All eight rods are now resized and the pistons are ready for new rings.

I am using Total Seal rings with a gapless top ring.

Hi, Ted. With a max of 15 pounds of boost, I set the end gap at .029". I am used to seeing an overlaping gapless ring, but these came with a bottom grove to hold a rail ring.

Note the 20 or so gas ports on the top of the gapless ring.
Just a shout out to John Mummert for some amazing pistons that were made to order some years ago.
