I'm not so sure of that. The old flatheads left plenty of room under the hood;
mostly above the engine. So did the old inline 6s from the 1950s and 60s.

As far as power is concerned, my '61 E-100 had a lot less power than my '40
Ford, and there were plenty of Falcons running around with that engine and AC. I
suspect that any small truck after the model-T era would do ok in this regard.

One problem you may have, though, is the relay that kicks the AC in. That's
usually 12v negative ground, and old Fords (at least) are 6v positive ground. A
replacement (and some creative wiring) might be needed.
