On you tube there are videos of the B&S v8 being built, running, and installed in a garden tractor. It has since been con erred to water cooling. Just search Briggs & Straton v8 on youtube.
The Studebaker DOHC engine was engineered by Leo Goossen and built by Indy mechanic Willy Utzman for a J.C. Agajanian car. When it was started in the pits with the auxiliary starter the snout of the crank snapped off. The car never turned a wheel in competition.
That was hard luck in deed,bet it would of been super*,after working bugs out,just no $$$$$ to play big by Studebaker ,an JC was in over load,with other stuff already.. I would of loved to see it go on,but was not to happen. The first hotrod V8 engine I looked for in mid 50's,when building my 28A*,with hopes of finding was a Sutdebaker V8*,,but found a Ford Thunderbird V8Y for free,so stopped hunting.! A little extra,too know before all that;; https://www.hemmings.com/stories/article/americas-best-v-8-engine-studebaker https://www.studebakermuseum.org/blog/studebaker-at-the-brickyard/
The you tube video about the Briggs & Stratton V8 show’s jewelry been build. Most impressive!!!! If that man every started building hot rods, I think many of us would switch to finger painting
The motor is installed in a 1969 Plymouth Barracuda notch back. I don’t know the current owner but there are some YouTube videos on the car, search Ball Stud Hemi 1969 Cuda Cliff Ramsdell
Here's a 1995 article, Dick Landy RIP, had one of the ball studs no doubt he got it through his Mopar connections.
I wonder if they pirated the rocker arms from something else or went through the effort of making new.
A little food for thought,you know that Studebaker you pay no mind too;;; be sure to click sound!! https://www.facebook.com/reel/2420088551670927
