The only thing I have close to what you're looking for is a 64 Imperial with a 413 (basically the same as a 440 but smaller bore). The MCC Detroit book has several pictures in it, but I'm not sure what you're looking for. The AC unit brackets bolts onto the water pump housing and intake in two places (front left of intake and the coil bracket mounting hole). Let me know if you want me to take photos of the Imperial. Hopefully someone with an E-Body big block and AC can post some pictures.
