Look into a junk yard gm 5.3. They have same bell housing bolt pattern as the gen 1 small block Chevy so all the parts from the engine back is the same as a sbc swap, Jimsperformance.com will do all the wiring and computer work for $500, and 5.3s go for $4-800 fully dressed. Tuned they make about 350hp bone stock.
I'm sure there is someone like Jim for ford engines, I just don't know who that is, also never looked into whether anyone makes the adapters to put a sbf in your rig.
