Ok, got some of the engine measured this afternoon with the help of a friend with really cool tools. Yes, I have tool envy.
Cylinder bores – Min was 2.5650 – Max was 2.567 on #4 - over MM 2.565 max
Valve Guides All were 0.3150 to 0.3153 - in the ball park
Valves stem 0.3105, 0.3110, 0.3115, 0.3115 - have some wear but smooth
Crank main journals 1.9870 - lost about 0.001" from new factory spec - looked good
Crank Rod Journals 1.5600 – 1.5607 - Lost about 0.002 to 0.0025 material - looked good but there was 7-8 thousands of gap with the bearings
Cam bearing 0.0018 – 0.0020 clearance to camshaft - looks fine
Piston Wrist pins had a fair amount wear that you could feel with your finger
Oil pump looked really good – 0.002-0.003” between gears and wall, gasket was 0.005” and everything looked smooth
