I think you mentioned just doing a hone on the cylinders, so you are going back with factory sized pistons? How did the ring lands on the original pistons look? Are you replacing your pistons with new ones? Many many years ago on my first engine rebuild I also opted to do a hone and keep factory size bores, it worked out fine but the piston to cylinder wall clearance was on the "service limit" spec which I wasn't enthused about since all the other tolerances were spec. Since then I always go one size over on my rebuilds.

The cylinders were in excellent condition and everything was within spec (a touch closer to tolerance than I'd like but it should be fine).
Im still planning on doing a hone and new factory size rings/bore. If the machine shop finds something I didn't find, Ill address it.

Copy that! If you decide you want to replace the pistons for some "0" mile ones I do have these I removed from one of my NOS 12ht's. That engine had some moisture intrusion from storage so I installed 1/2mm oversize pistons in it to clean up the cylinder.

For those who are curious, the next phases of the build are as follows:

1. Finish building axles
2. Get axles and springs mounted to frame
3. Wheels and tires on and roll chassis
4. Power steering arm and tie rods
5. Mount Engine, trans, and tcase.
6. Measure driveshafts and get shafts made
7. Body on frame
8. Wire engine, ignition, and lights

July 14: Project deadline. Come hell or high water Im driving this thing to Wyoming so it has to be done. I dont care if the floor is patched with plywood and my ignition is a light switch. Its going.

Before you get to far down the road it looks like you have an issue with your springs, "The arrow is meant to point towards the fixed end on the frame opposite of the shackle." Additional info can be found here.
Thanks for catching that! I figured they pointed forward. I shall correct that!
