Hey all. I'm workin on a 1989 Chevy truck with a 4 bolt 350. Block is cracked, got another but didn't notice it wasn't a 4 bolt. It's a 2 bolt main. My question is can I use my crank from the 4 bolt block in the 2 bolt block. Are journal sizes different? I will be using the rods and Pistons from the 4 bolt in the 2 bolt.
