what size engine came standard in the 1978 F150 customcab witrh auto tranny
i dont believe there was anything standard, you could have a 300 straight 6, 302,351M,400,460 and i probably missed a couple on the 351's, i would just right down the Vin and see what that would tell you about that particular truck, i think a nice ford parts guy could explain it or try looking on the internet for what all those numbers meant.
