Hi
My engine rebuilder for the 1948, 320 cu in does not have the main bore diameter dimension.

Does anyone have this?

Thanks
Tom

If you mean the main bearing journal diameter, my Motors Manual lists them as : #1-2.5605 to2.5615
#2-2.6235 to2.6245 crank. end play:.004-.008
end thrust taken on #3 main bearing
#3-2.6855 to2.6865
#4-2.7485 to2.7495
#5-2.8105 to2.8115
rod bearing journal diameter :2.248 to2.249

main bearing clearance :.0005-.002
rod bearing clearance: .0005-.002

cyl. bore :3 7/16 in.

1948 and 1949 list the same specs.

Thanks for the info.
Apparently the rebuider wants to aline bore the main bearing surfaces. But I have not seen a dimension for this.

Thanks
