if money id not an issue, id go with oliver connecting rods and diamond pistons, My dad has this 1968 dodge power wagon with a 1200 horse power 540 wedge. I know im compoaring apples to oranges here but id go with the oliver rods cause thats what im doing this winter in my big block dart and same with diamond pistons. if you spend a little bit more money up front then you wont have to later on, and id use a new crank, also just for insurance
