427 CBB oil pressure

[Mike Taylor 3601]

If you dont know what bearing clearances you have I would check them most likely they are a loose, you can test oil pump by taking old main cap and tap it to accept gauge where oil come from pump,stick in bucket oil spin it w/drill and can see what pressure pump is bypassing at,have someone help hold it or mount to bucket it's hard to hold by yourself.
