OT car however the engine isn't, 500hp 18lt WWII Ford GAA 60 degree V8 Sherman tank engine, DOHC 4 valves per cylinder http://www.amcarguide.com/custom/1969-mustang-fastback-with-tank-engine/ http://www.fordgaaengine.com/ http://www.theshermantank.com/about/the-sherman-tank-engine-page/the-ford-gaa-data-page/
Picking up where I left off, https://www.jalopyjournal.com/forum/threads/unusual-engine-photos.1123661/page-34#post-12991062 The induction on the OHC engine on the bottom of p. 30 appears similar to that used on the experimental 1961 Pontiac Tempest Monte Carlo that was fitted with 195ci Pontiac four cylinder engine (1/2 389ci) and a Mickey Thompson supercharger system (GMC 3-71 blower) feeding the carburetor and adapted to the blower with a special elbow. Hot Rod Magazine produced ant article in March '68 on Pontiac' overhead cam (OHC) V8 engine and one of its first 'Cammer' engines. This test mule was built in late 1963 using a basic 389ci block and fitted with unique 4 valve per cylinder heads with dual overhead camshafts (DOHC) and a special cross ram intake manifold fitted with sequential port fuel injection. It never progressed beyond developmental testing.
OMG, an air cooled flat 10 Impala engine based on a Corvair flat 6. Purportedly this power train led directly to the development of FWD Oldsmobile Toronados as it had been experimenting with FWD cars from the late 50s and seriously contemplated building a FWD car in or about 1961. The rest they say is history. OT marinised LT5
I've searched HAMB and this thread but haven't come across it yet but here's another Mickey Thompson experiment. What didn't he try, 427FE and Pontiac hemi heads etc. This time a 3-valve per cylinder SBC Indy engine. 565 horsepower with 305ci. https://www.enginebuildermag.com/2018/10/eotw-mickey-thompson-3-valve-chevy-v8-indycar-engine/
Another shot of the Stephens OHV conversion posted by Loudbang. https://www.jalopyjournal.com/forum/threads/unusual-engine-photos.1123661/page-27#post-12878335 Only 3 or 4 sets are said to exist, here's one set in Gene Palmer's hot rod.

Another rare one in the Museum of Speed, a DOHC V8 Studebaker https://www.museumofamericanspeed.com/1953studebaker.html
Here's a rare NOS 350SBC Hemi that was listed on E-Bay in 2014, with a starting bid of $30K. Where it is now is anyone's guess https://www.ebay.com/itm/392-HEMI-N...=true&nordt=true&rt=nc&_trksid=p2047675.l2557 http://vi.vipr.ebaydesc.com/ws/eBay...descgauge=1&cspheader=1&oneClk=1&secureDesc=0 Engine came complete with a plethora of parts and documentation to support its providence and authenticity. Purportedly the Museum of Speed has one of these engines as well however I can't seem to locate anything on it. The heads featured hemispherical combustion chambers by Leo Lyons and came equipped with fuel injection and a magneto. They were built for drag racing and roundy roundy tracks. Speedy Bill Smith allegedly purchased his engine from Mauri ROSE, who was planning to run it in the Indianapolis 500. https://www.speedville.com/leo-lyons-chevy-hemi-pops-ebay/ This was the Museum of Speed link on it's engine however it's not currently active. http://www.museumofamericanspeed.com/Chevrolet-Small-Block-Leo-Lyons-Hemi-Head-Conversion,9115.html A did a bit more research and discovered some trivia that pieces the puzzle together, ROSE may played a part in the R&D:- Post WWII, he was an engineer who just happened to be a race car driver; and After retirement he returned to engineering full-time with a number of enterprises including GM where he helped Chevrolet establish its presence in both hod-rodding and stock-car racing. These hemispherical heads are totally different to the rare factory GM 302SBC hemi heads I posted earlier (#1004). Carb intake as well as fuel injection intake. I can't locate anything else on this rare engine apart from a 2014 HAMB post where it was listed for sale, hasn't been on forum since 2017, for $60K A quick flip and profit, maybe? actually he's the same E-Bay seller. It was also featured on Bangshift. https://www.jalopyjournal.com/forum...st-chevrolet-hemi-all-aluminum-engine.939289/ https://bangshift.com/bangshift1320...-rare-speed-parts-ever-never-assembled-freak/ .... 1 of 3 known to exist LEO LYONS ORIGINALS!! There's one in the Museum of Speed, owned by Bill Smith. The second is in private hands of Walt Austin, and BOTH of these are cast iron block engines.

I wonder what that gizmo is sticking out of the rear of the RH cam tower on the 1931 Bugatti Type 54? Maybe a magneto - adjustable from the driver's compartment?
Exactly, mag drive shaft to cockpit mounted mag. And check out the robust right angle gear driven blower case.
