I'd take some very careful measurements first before assuming it is a bolt in. Worry about height, length, and width at engine mount height and cooling outlet locations. What are you going to have to do to get the electronics grafted in to the wiring harness? What about starter/exhaust fitment and oil filter placement? Access to belts and hoses? Then you get into "the might as well". I currently have Wilkinson installing a 5.4 mod motor in mine and it isn't exactly a bolt-in many thousands of dollars later. Granted I have special circumstances with a dry sump, supercharger, clutch change, and starter location modifications.
