68 SS 427 NOVA??????

[sixtiesmuscle]

What dealers doing conversions were within "several hundred miles" of where it was bought? That seems to be an interesting clue. It also seems that some people back then got sold on the idea that the L78 was "just the same as" the 396/425 from late '65. Pretty soon, their 396/375 became as good as a 427/425 in their mind, and, sometimes in conversation. Don't forget, there were some with these two engines who would have swapped air cleaner tops [decals] with each other for opposite reasoning.
