Same block different oil passages to the main bearings. 31 main bearings are oiled through the crank, 35 is oiled through the block. If you put a 35 crank in a 31 block it will seize up due to the front main bearing not getting oil. Everything else is the same except rods and crank, 31 has a shorter stroke. Also wouldn't recommend mixing 31&35 crank and flywheel, you will have vibrations |
