OK. I have done a search on this question and am still confused.
I scored a 1952 Chevy Truck 235 motor in pretty good condition. On a complete tear-down it shows only light wear in the cylinders, the valve head did need a new head gasket --- here what my question is.
Each main bearing only has a single shim installed opposite the cam side of the main bearing caps. These are NOT laminated "stock" Chevy shims.
This motor has .010 under-size mains, so prior crankshaft work was definitely done (and the crank still looked pretty good).
IF I bolt the main bearing caps back on WITHOUT the bearing inserts in place , without any "shims", torque to spec : should the measurements I get show the main bearing housing bores (saddle bores) to be concentric (round) . OR should those main saddle bores show eccentric (more or less at crown than parting line)?
I can't figure if I am working with 1952 "stock" main bearing bores , or some latter machine shop align boring on them?
