Was trying to get more info on this engine. Doesnt come up as good # on parts sites. GM#14088548 come up as years 86-94, 2 bolt or 4 bolt main. Front pad #VO1166AB. Was curious if 2 or 4 bolt main and 1 piece or 2 piece rear main. Should be 1 piece. 20230908_080911.jpg20230908_073051.jpg

As far as which bearings. 90% are 2-bolt bearings. Run the block casting number and you will find it listed for both

The block casting number will also tell you if your block is a 1980-1984, 1985, or 1986-1987.

1985 and later is 1-piece RMS with perimeter bolt valve cover, 1986-1987 is center bolt
