whats up fellas, im am a new member to this forum i have a 1990 bronco full size runs real good,but im interested in doing a motor swap and also doing a front end swap for a 92-96 front end,my question is can i use a motor out of the newer f150 above the year 2000? and can the front end swap be done from the 92-96 bodies.  

I don't know how well the new modular motor would fit in the older Broncos. They're pretty big dimensionally, about as big as the old 460 big blocks.

Your best bet is probably finding a re-built 351, or buying a fuel-injected performance crate motor.  

First I would put in a 360 or 390. 400m and 351m only last 2yrs. Front end I would put dana 44 from a 1977-1979 f150.
