I have three 4 cylinder Diesel blocks out in the shop. All have 3.90" bores so they are 172's- not 144's.
Note: All of these have Sleeves and Cannister style oil filters.
310609 cast June 19, 1958 (86T date code). No crankshaft balancer and no teeth on the crank to drive a balancer.
B9NN6015B cast March 10, 1960 (0C10 date code).
C0NN6015C cast September 29, 1960 (0J29 date code).
I had a C0NN6015? block with no sleeves and a spin-on filter but I must have sold it because it's not here now.
