Maintaining a 1.4hp/cu-in is different than 1hp/cu-in or less motor that's regularly driven on the street for the average Mopar owner.
Back when MP sold those 380hp crate motors.... most people had eyes bigger than the stomach and bought those instead of the 300hp. And sure enough year or two later customers come back asking about dual planes, EFI, other ways to detune them. This is from ns1rm21 that was a top seller of those at Westoaks MP.
