I have been taking apart the EZ30R motor that was in Jeff’s SEMA car. It sat for a number of years, and probably has 5-10k miles on it.

The main bearings looked fine.. very little wear, and no significant damage. The rod bearings were trashed. Pitting in all of them, significant surface wear, and uneven coating. The cranked looked fine, but might need a polish.

Next up I’ll re torque the case and measure the bearing clearances as it sits now, just to know how to was. I’ll also measure the piston to cylinder wall clearances and the rod clearances.

The pistons look fine. Very little side wear.. lots of carbon on the top, but not surprising as the car sat for years with very little run time, lots of small starts, and lots of time with rich mixtures. I’ll get new pistons only because I’ll have the bores cleaned up a bit. This is a sleeved block, so easy to overbore a tad.
