Best Answer

You go with a 350 instead.

You need the engine with it's computer chip (you can place it into the v6 computer), knock sensor, injectors and TB unit, but since you are getting a complete 350 (and bypassing the 305), you'll have everything you need.

Move the v6 mounts up a few inches to the v8 mount holes and bolt back in.

Drop engine in place.

Done.

To change a 460 Ford engine and make it displace 351 cubes, you would have to remove the 3.85" stroke crank, and install a crank with a 2.94" stroke. I do not know how to change the year on the engine.
