For those rebuilding a Standard Flange (Narrow Deck) O360 the main bearing listed first in parts catalog PC-106 is part number LW11020. This is a bearing for the Wide Deck engine and will not work in the Narrow Deck case. This bearing can prevent the case from closing by as much as .020". I learned this the hard way.
The correct bearing for the Narrow deck case is LW 10124 and is listed in PC-106 as an Alternate bearing.
The difference is the Wide Deck bearing has a round location hole and the Narrow Deck bearing has an elongated location hole that allows for variables in location of the bearing dowels.
