What spark plugs should I put in to my '65 330FT?

Looks to be the typical plug gap for points, .030 to .035, you canuse for the most part whatever plugs you want that fit properly.

Ok, did a little searching, and got a little more for you, it is all the original Motorcraft parts from a user by the name of Numberdummy, liberated from another site.
