They Never Installed a 427 In Anything But a GT-E in 1968. Except When They Did… Okay, so what if I told you that there was this guy who says there was a ’68 XR7–that’s not a GT-E–built with a factory W-code 427 (impossible), has factory Whisper Aire® Air Conditioning (not available with a 427), painted white (of course, all unicorns are white…), and that it was ordered by a dealer in Texas for a retail customer, built on the assembly line, and it may still be in the hands of the original owner?
