1964 SOHC 421 Pontiac V8 Most likely prompted by its development of the Pontiac OHC six, the GM division built three different experimental SOHC 421 CID V8 engines in the early 1960s. According to the engineers who worked on the project, the SOHC 421 engines produced around 625 hp and were capable of turning 7,000 rpm. One version of the engine featured camshafts driven off the front of the engine, another design had the cams driven by gears off the back of the engine. Here's the engine in a Pontiac Engineers's car SOHC 427 BB Chevrolet https://www.hemmings.com/blog/2015/...head-camshaft-and-hemi-headed-big-block-v-8s/ https://www.hemmings.com/blog/2018/...big-block-chevrolet-heads-turn-up-at-auction/
I took photos with an early digital camera on that trip, something messed up on it and I lost most of my photos of that auction. But the things we saw were amazing, the technology even back then.... or an attempt at modernization. Bones

I'll be the odd ball again. Here is a Stanley Steamer engine probably 1895. My partner in our railroad endeavor has two of these. If I was a little younger and had more time I would build a car for one of these
1960's GMC Toro-Flow Diesel. Note both the intake and exhaust ports on the outside of the cylinder heads. The injector pump took up too much space in the valley.
1908 Aries 1413cc, 100x180, OHC with 4 desmo operated valves, 4 plugs and a rotary sleeve valve primary induction. 33 tall. Turbo Offfy
A V8 with U-flow heads? Now this six cylinder aficionado has seen everything! I've been working for years to eliminate the "toro-flow" heads on my sixes. Like we used to say in the automobile industry, "If you can't fix it... ...feature it!"
The Millers were truly works of art IMO. In the 80s I belonged to the National Auto Racing Historical Society (now defunct) and our group did a video of Myron Stevens and his metal working skills. He shaped a track nose on and was available on VHS. Myron Stevens did the majority of the metal work on most of the Millers during the 20s and 30s-amazing craftsman like the other Miller men. During the interview I believe he said he made the headers from a flat sheet and the first set took him 40 hours. I have studied his headers at the Indy museum and they are also works of art. Funny aside when I lived in San Marcos Ca. in the 80s there was a race car for sale northeast of me in the mountains. The guy raised peacocks and I drove a 74 Vette with a custom paint job to take a look. The guy let me in the gate and his birds used my car as a mirror and were admiring themselves which was a first for me to witness up close. The race car had a model B Ford engine with some modifications as I seem to remember with a non original grill but allegedly a Myron Stevens tail. I removed the seat and studied the interior of the tail and you could see hammer works that almost looked like they were made by a machine. At the time the car was not worth a fortune (neither was mine to be honest) but the owner offered to trade me straight up for my Vette . I turned him down (DUH). Wish I could go back and kick myself in the backside and do the deal.
That's a Peerless 60 (a cool car in its own right). They only made three Fageol cars before America entered WWI and the Hall-Scott aero engine that powered them was needed for the war effort. None are known to survive.
Semi-Hemi is an oxymoron. Just because an engine has overhead valves, canted to one another does not make it a hemi. A hemi has a combustion chamber that is shaped like half a tennis ball, actually half of a sphere. Most “semi-hemi’s” are in fact pent roof chambers.
The new Dodge"Hemis" are not hemis. They have canted valves in a bathtub chamber with two quench ledges.
Marketing thought that was too wordy. Plus, there wasn't enough room on the trunk lip for a badge with all that.
