Lm7/LS Measurements over the last couple nights:

Reluctor wheels’ runout. Minimal. Well under spec.
Main journal clearance: .0015” (plastigauged)
Connecting rod clearance: .0015” (plastigauged).
Crankshaft mains’ runout: negligible/nonexistent.


Things are looking pretty good as I move forward here. Next up: Piston ring installation and insertion into the block. This reminds me; I need a new piston ring compressor. My old one fought me with the 261 in the 1 ton GMC.
