What engine is in my 1945 BN ?

jCarroll · Oct 16, 2018

Obviously not the original. On the right side of the block there is a crankcase dipstick under the number 4 cylinder.

On the smooth place under the #1 plug are these stampings:
upper left corner: IMAM
upper right corner: G
lower left corner: 4 3 97

Thx for your help,

Proably came from a swather,combine or just a power unit did not come from a tractor. What is the part # on the block it could be a 113,123 or a 135 cu in engine and that you will not know until the head is removed and you can measure the bore
