clevite 77 bearing number 3 66 CB 386P...can you tell if that is standard size by that number...........thanks yall ....dewy
 
do you have the brgs. in hand or just the number? the brgs will have the size stamped on the back side. like .010,.020. standard size has no stamping.
 
that is true also. guess you will find out when you install them , if the crank wont turn once you torque the rods, your in trouble. should be able to check the thickness with a caliper against the originals.
when i was 18 i put rings and brgs in my 67 chev 1/2 ton. the parts man says how many miles you got on that engine? i said about 100,000. he said you need .002 undersize brgs. like how am i to know. so put them in and engine would not turn over. what the heck! so took them back out and went back to parts man and got standard brgs. all was good then. that was over 40 years ago.
