By the way, the machinist's suggestion was that the engine was assembled by 'inexperienced hands' and not kept in a clean environment during the process. For only 2300 miles, I wouldn't expect this much wear, even with hard use.
Also, I found that about half the main studs were torqued to over 150 ft/lbs! Shelby spec is 85. Can't say accurately whether the rods were over-torqued or not. Lots of silicone sealer is used on pan, intake and other sealing surfaces. Oil galley plugs were super tight - not corroded, just tight.
The main caps are cross bolted, but with only grade 8 hardware on the sides. This will be replaced with ARP or similar if available.
Bores have some scuffing on the thrust sides but crosshatching is still visible.
