Probably the only difference will be the passages behind the power valve, you may have to slightly enlarge them for the 850 enrichment. Another thing, you stated an old 750, see if your carb has down leg boosters, you may have an old 780 carb (3310-1) and may be sought after by some.

A 750 will have the straight boosters and have 3310-2, 3310-3, etc... The 780 will have 3310, 33101 or 3310-1.

The 3440 block is actually off a 2 barrel Holley, I think used on a Ford tri-power set up. The internal air bleeds will be in different locations and have very small power valve feeds. It will bolt on but you'd have a heck of a time getting it tuned to work on an 850.
