The hot rod with the owner in the leather jacket, has a modified Ford flathead. I feel those are Ardun heads, engineered by Zora Arkus Duntov, man later to work on the Chevy V8, with the Duntov cam. Turned the Ford into a overhead valve Hemi engine. Developed to boost the HP of Ford truck engines and cooling, then hot rodders found them. Believe the leather wearing owner is Ed Iskendrian, builder of the Isky camshafts, famous with hot rodders. The photo of the 64 Chevy engines is nice, I recall a sweeter time when all chevy engines were Orange. The initial "Z", from Zora, was later used on the Z-28 Camaro, also because of John Z. Delorean, a GM Vice president at the time. Before he built the stainless steel car. Dang, did more searching, those cyl heads were Iskendrians own, the car still exists. Did find more info on the Ardun heads.
