This was a interesting thread.To me at least. Maybe some new members have more to add or would enjoy reading it.
Take a look here.. http://www.museumofamericanspeed.com/Collections/Engines/AllAlphaE038.shtml Complete article PDF http://www.harveycrane.com/images/hotrod_0871.pdf I always wanted these for my Jag..or a Traco alum motor.
Moser DOHC conversion for SBC ca 1971 - Tom McMullen had one in one of his cars - may have been in his roadster at some time.
Gurney-Weslake heads for small block Ford were pushrod with shaft rockers (inline vlaves, not canted) but had radically raised intake ports, and the injectors or webers bolted directly to the head without an intermediate intake manifold. There was a seperate valley pan. The exhaust ports were also raised to the point that they did not work with the shock towers of the production Fords of the era. Gurney Westake also produced a DOHC V-12 engine for their F1 efforts.
Didn't pontiac do something like dohc with their 6 cylinders that went into tempest/le mans? I think 68 right?
Allison and Rolls made some nice OHC engines back in the mid-1940s, but the displacement, at 1710 cu in, is a bit too high for a car. Oh, and they are in a V-12 configuration, so it might not fit between your Duece rails, radiator and firewall. ;-)
1953 Pegaso Z102B - this is actually a V8 3.2 liter four cam engine, gear driven cams with very rare dual quad Webers. The car also feature a torque tube, rear mounted ZF 5 speed with inboard brakes. The Z102 first appeared in 1952. Impressive for any car of that era, let alone a road going grand tourer.
Don't know if it's been metnioned as I haven't read all the posts, but here's the English Triumph Stag SOHC V8 from the 1970's. Plagued with overheating and warping problems at birth, many of these were swapped out for anything else that would fit in the engine bay, but modern technology has solved all the issues and the engines can now be built to be reliable. Absolute screamers, 6700 read line, 3 litre, all aluminium I think, certainly alloy heads. Backed up by a 4 speed manual with overdrive. Almost 3000 of them were imported into the US, so they may well be around in old scrap or wrecking yards. Cheers, Glen.
I just posted a copy of my global matrix of V8 engines, OHV and OHC, and some early DOHC V8s exist. The 303 Miller. The Novi Indy of 1941-66. Mercedes GP W165 of 1939. Both supercharged. Alfa's Trevisan prototypes of 1937. Czech air-cooled Tatra 603. Riley Autovia was high cams in block. Goossen Indy Stude of 1952 was the finest work, 4 valver injected, and is viewable in Bill Smiths Nebraska museum. Something similar on a DeSoto from the same designer. The Lancia GP of 1954 and 270 inch Maserati 450S of 1957. The Ford 1100 cube Sherman tank engine. The Coventry Climax 2.5 litre GP of 1954.
If you wanna inquire on any of the above, feel free to query my Facebook blog, called Looking Back Racing. It pulls up in Googlesearch.
My great friend Rabbit originally from Melbourne Australia now Dahlonega Ga. dynoed every one of these.
Wills St Clair was an American made car , 1921 - 1927 . They were equipped with a single over head cam V8 .
Not a regular production street engine https://bringatrailer.com/2018/04/26/technically-interesting-ford-indy-dohc-v8/ Original design parameters indicated sustained 8000 RPM running. Final specs included a 3.760″ bore and 2.87″ stroke for total displacement of 255ci, and running a 12.5:1 compression ratio the so-called Ford Double Overhead Cam Competition Engine delivered 495 HP at 8300 and 330 lb. ft. at 7000–for qualifying the redline was extended as far as 9200 revs.
