I have a local friend who is an old Mopar guy from way back. He SAID he put a 440 in a 65 Barracuda in the late 60s using log manifolds and fabricated mounts. He's a welder by trade and a really GOOD old school welder, so the mounts I can see. I never questioned him about it, but I cannot see any way in the WORLD any manifolds would fit a 440 in a early A body.
