After pulling the engine last November and finding small chunk's of plastic or some other type of material in the screen on the pick up tube, and also the condition of one of the connecting rod bearings, I didn't think I had any other choice but to do a complete rebuild.
The crankshaft was not machined, because I learned when these cars were built, the crankshafts received some type of specialize treatment or coating (I don't know what it's called) from the factory. If I were to machine the crankshaft, that coating would've been gone forever.
The journals did need some attention but not too much, so an Emory cloth was used to clean them up, by using 320, 400 & 600 grit, as seen in the pic below.
When
@Xenon and I were setting the crankshaft oil clearance, it was set to 0.003 by test fitting the clearance two times, using Plastigage.

The machine shop that did the heads milled the base by 0.020, installed heilicoil's in the valve guides and did a valve grind to the valves & seats and then vacuum tested.
The block was hot tanked, and had new cam bearings as well as the tower shaft bushing installed.
The cylinder walls were not bored out, but were cleaned up using a ridge reamer and honing tool at my shop.
Comp Cams Xtreme Energy 3 bolt cam # 145-1224 (440Source) was chosen for the build. New main bearings, connecting rod bearings, 3 bolt double roller timing chain # 102-1002, the Melling HV oil pump, and chrome molly push rods, Stealth cylinder head valve springs are some of the other parts that went into the engine build.
When this project is finished, I will name all the vendors that had been sourced to get this car to where it is today.
There are quite a few. My receipt folder is as thick as Gideon's Bible.
