    3394 case IH Engine swap

    I have a 3394 engine with a spun rod bearing. I can get a 2594 engine for it, they are both A504DBT engine but the 3394 is MFD and the 2594 is 2 wheel drive. Is this block going to bolt up? It looks like the 3394 block has extra holes on the front but only have picture of the 2594 engine. Thanks
