GM - Oldsmobile Viking (1929-31) monobloc V8 1929, 260ci 81hp. By comparison a 1932 Ford V8, 221ci 65hp https://www.macsmotorcitygarage.com/1929-31-viking-a-lost-general-motors-brand/
I've seen plenty of Offy's but never noticed one with this oversized crankcase breather before. Maybe a little too much nitro in qualifying? I think a lot of teams snuck in 10-15% BITD.
Davies produced 10 of these DOHC flathead conversions I stumbled onto these, possibly an assembled Davies or Ansen conversion. Below engine does not have a belt drive yet mock up does? Ansen conversion in lower left foreground with drive, were they the same as Davies conversion, no knowledge? Below picture depicts gear drive set-up. Note a young Ed Iskenderian on the far left of the group!
I ran across a photo of a similar engine with different carburetors, it was ID’d as a Chris Craft Model M, 130 hp, built by Hercules.
The first photo is Joe Lencki’s Gallivan, but instead of using a Model T block as was customary Joe designed and had his own block cast. It ran at Indy in 1935, went out with a bad valve. The other engine is a 248 cu. in. Morton-Brett. In qualifying at Indy in both 1937 and 1938 it was waved off for having insufficient speed, never to be seen again.
Looks like the intake manifold and updraft carbs are below the openings that you can see the springs in... they look like access openings and would be above the intake ports
Is anyone else frightened by the thumb-screw hose clamps on the oil and water lines on the Lencki engine?
Yes they are thumbscrews but there’s nothing to prevent one from tightening them a bit more with pliers. How about the wire clamps on this 1926 Indy entry, with an engine by Ernest Eldridge of Great Britain? This was a common clamping method and even the Duesenberg brothers did this early on.
How ever did I miss this thread? Here's one for the thread, a Dodgeson rotary valve engine built around 1923. It was built by a son of one of the Dodge Brothers' sons. He tried to build his own car but was not very successful.
The Military has always invested into various development of engines for their various applications. I had a customer for 30 years and that was his entire business, some the most interesting work I did, I built many interesting projects that I'd like to talk about, but this type of work came with a confidentiality clause, we turned in all tooling/drawings/parts/concepts/cad cam computer files/etc. After a project was completed, Twilight Zone, Gone
Love this Thread, It shows that near every design concept in engine engineering has been done, many from way back in the day. Our modern electronics combined with technology produce engines with unbelievable power and economy. I put up pictures of my build project completed and used in competition 1984-1986, still have, expensive paperweights. I was racing Midgets, using VW style racing engine, as far as I Know, the only liquid cooled cylinder head for this application, timing is everything, was used, very competitive, engine rule change and It was all done for me and this concept. by wicarnut posted Jan 20, 2014 at 5:00 PM by wicarnut posted Jan 20, 2014 at 5:00 PM
No, look closely, the tubing is held to the cylinder head with banjo bolts and drains the head to the oil pan. There is a third bolt obscured by the steering box and probably one last one too.
Thanks Fordors. Care to shed any light on what looks to be a blow-off valve? Is there parts removed (turbo???)
Just NE of the red arrow it looks like that’s a Roots blower with a single carb, probably bevel gear driven.
Alden Sampson is seen with the 16 cylinder engine Frank Lockhart created from two 91 cu. in. Miller straight eights. Riley Brett used the engine in a 1929 Indy effort that DNF. Brett rebuilt that car and engine for the 1938 Sampson Special.
Early in this thread I posted a photo of this engine, but this one shows more detail. The Harry Miller built Gulf Oil effort was not only rear engine but also four wheel drive. Six cylinder and Roots blown Miller later added a second Winfield carburetor and an intercooler.
George Barringer is seen with the Gulf engine. Looking at it, like all of Miller’s designs I’m struck by the beauty that Miller turned out. Harry came up with the concepts and Leo Goossen his engineer/draftsman, and the pattern makers and machinists that completed the projects were truly artisans.
