Wow thanks Jack. I'm still trying to wrap my head around this. For example, the top photo shows three carbs, two in back and one in front. Did some air / fuel get inducted into the rear carbs and directly into the crankcase and other air / fuel get drawn into the middle cylinder and then force fed to the other two? All three jugs look to be of similar bore.
Later designs were apparently true triples. 3rd cylinder converted from a supercharger pump to 2-stroke combustion.
^^^. Great pic wonder what year. Still appears no true expansion chamber exhaust. Guess they came later
The expansion chambers on the DKW are not the most common cone to reverse cone style but are expansion chambers just the same.
I met Pete 25 years ago at the Pomona Fathers Day Swap Meet and Show. In his booth there were at least 10 engines all with overhead camshafts. We talked about a GMC six but the SCTA rules didn’t allow them unless you ran heads up against cubic inches. I don’t think there was an engine he wouldn’t put a set on. We are currently the same SCTA Member club. I’ve admired everything that man has done..
Many cam manufacturers will grind one-off cams for projects. Of course they could get pricey as setup costs are significant. You may have to supply the cam blanks too.
I'm not sure how to classify this engine, but it was running strong on the "circle track at the Big Knob Grange Fair this past week! Seating for four drivers! It might be a little too big to enter in the valve cover races.
