It should be a internally balanced engine if its the stock '78 460. 1979 is when Ford externally balanced the 460s which were 1979 to 1996 -'97.

Yeah, one way you can determine if its external or internal is the weight on the front of the crankshaft behind the harmonic balancer. There should be a Hatchet shaped weight for externally balanced 460.

there is another way to tell if it is internally balanced. look for numbers on the crankshaft. 2ya , 2yab, 2yabc. those are internal external numbers are 3ya , 3yab, 3yabc.
