Miss print or not .00025 ( 25 hundred thousands ) or 1/4th of 1 thousandth is not enough clearance. Oil is needed for lubrication and cooling of the bearing. While tight clearances will help keep oil pressure up, too tight and the bearing will burn up. Plastigage is not super accurate but when used correctly is a good way to check or double check clearance. .001 to .002 is a good rod bearing clearance for a street driven Studebaker V8. I was looking in a 59-64 Studebaker shop manual for rod bearing clearance for 63 and 64 Jet Thrust and Super Jet Thrust engines, the Lark and Hawk version or the R1 and R2. It shows .0005 to .002.
