The A&A manifold is based on the 1964 intake. They make it in 3 versions. As cast 440 ports, cnc 440 ports and as cast max wedge ports. I'm pretty sure Guy replaced a Mopar performance reproduction manifold with the A&A and picked up a tenth or so. He is running the max wedge port intake.

Getting old just means you were smarter than some and luckier than others.
