main bearings

[Bens340]

ok i know it might not be "correct" but im not ready for a full engine rebuild yet. has anyone just replaced the main bearings in a 3rd gen b body in the car just by dropping the pan? id love to just be able to do this without pulling the engine, spending all the money and having the car be down for however long it would take me between work and my little man running around. the car runs great but has had lower oil pressure as long as ive owned it with some slight knocking from time to time. i also run 20/50 to limp it along. if this gets me a couple more years then ill be happy.
