I used to have a 93 F-250 with the V8 460 and I inquired at the dealer about block heaters and found out that after factory has one element that goes in one of the block plugs and that you could add more than one so that you had one on each side of the engine. At the time they had told me that the factory ones used two of the knockouts but that you hadta buy 2 after factory ones to make it exactly the same. That being said I don't know how accurate the parts guy's statement was, but that might explain it.
