That looks great!

Why don't you want to use a differential close to the original 3.07?

Are you planning on hauling lots of weight about? Or will this just be a cool ride?

FYI

The OM617a was eventually mated to a 2.88 differential

The non turbo OM617s had 3.69 diffs

The OM616s (non turbo 4 cylinder engines) had 3.46 diffs

EDIT:- the benefit of keeping the existing differential ratio (if at all possible) is that it will be easier to set up your 722.3 transmission - the data in the FSM transfers straight across
