I have a 1999 F-150 with a 5.4 and I was wondering if a 460 would fit in there?

Also how much power does it have stock?

 

The 460 stock produces 235 HP and torque is about 370 ft/lbs , if my memory is correct . I know the HP is right .

Your 5.4 is lighter with about the same specs. and way better fuel economy . I think you should go for mods on what you already have .
