A friend gave this to me, and he normally deals in Galaxies and Thunderbirds, so is likely a 428 part, which would make it the C6AE-2B290-C. The Mustang 1967 390-4V would have used C6OE-2B290-C. What about the GT500 428 PI engine - which of these would that have used? The 428 PI drawing shows C6AE-2B290-C, but that is geared towards a police car not a Shelby.The 67 GT500 would use the same part as the 67 390 4V in this instance. FYI the 67 GT500 is the same 67 428 PI engine but with duel fours added.
