Would a crate Romeo 605 or M-6007-C54 physically fit into a 2002 2wd Super Duty engine bay without cutting the A/C box or the upper cowl? Would the steering clear the DOHC?
These are Ford Racing Parts crate 5.4L supercharged DOHC engines.

 

With the 3-valve 5.4 going into the Superduty in 2005, I'd imagine it would fit in the 2002.

The only way to tell is to measure, I haven't heard of a DOHC motor in the Superduty (yet!).

You could find a Navigator motor (DOHC) to check on measurements.
