@ sideoiler427, I spoke with Jeff (1985 CCX) a few week's ago about my date-coded 1965 C5AE-H-block. I have complete history on this motor. As mine came from Holman & Moody to be installed in 66 Merc. stock car, Project was shelved in late 65, and a crew chief from Holman & Moody brought the 427 that year, where it sat (Crated) in his garage up till 5years ago, until the org. owner of my CR (they were friends) brought and had it freshen up here in Wa. state. All number matching (LeMans crank & rods), and just dyno time, I was some what surprised at the value of mine. But then again it would have to go to the right buyer for the kind of dollar figure we discussed (Such as a owner of a real car) As Jeff and I discussed mine could be installed in a full comp Cobra, or in a Ford GT-40 Mk.2 (By the date codes). So I believe that adds to the value of mine. I still believe the value is anything the buyer & seller are happy with, as Gaz64 said, come up with price for your new motor and go from there. My $.02 I would keep that motor
Nothing like a Sideoiler! Cheers Tom
