Can someone with a parts book > look them up for me?? Rods with bolts were used up to engine 1100000, the end of '65. I think there's an error in my microfilm; I don't have a good number for the rod. The late one always has 311B cast into it, so I expect it to be a 311 xxx yyy B, but what the microfilm lists is 311 198 401 which has got to be a repair kit of some kind. In fact there's the implication that this is a kit of nuts and a bushing for a rod (or set of 4 rods....) > The crank is a .010" undersize, on both mains and road bearings, and the > case is line bored .020 oversize with a cut thrust.

Cylinders sinking into the case? Other cylinders have shims? Alignbored off center? Crank cracked and wobbling? Different pistons with different pin heights? (Perhaps indicative of J C Whitney quality.) Interesting. I remember the engine.
