Harry is a race engine legend. He was responsible for the engine that became the Offenhauser...
From Wikipedia:
The Golden Submarine was built from aluminum with holes for the driver to look out.[3] The gold color was achieved with a combination of bronze dust and lacquer.[2] The car cost $US 15,000 to build ($299,000 in 2020).
Specifications
The car featured a four-cylinder aluminum alloy engine with 289 cubic inches (4.74 l), 3-5/8 bore × 7-inch (180 mm) stroke, 136 hp (101 kW) @ 2950 revolutions per minute (RPM), a single overhead cam, desmodromic valves, dual intake ports for each cylinder, dual spark plugs and magnetos.[1] Its body and chassis were wind tunnel-tested aluminum body with rollover protection. It had a 104-inch (260 cm) wheelbase and it weighed 1,600 pounds (730 kg).
Race history
The car made its first outing on 16 June 1917 at the Chicago Board Speedway in Maywood, Illinois.[4] The engine failed after 10 miles (16 km), but it averaged 104 mph (167 km/h) up to that point.[4] The engine problems were ironed out the following week and on 25 June he defeated arch-rival Ralph DePalma three times on the Milwaukee dirt track.[4] The car competed in 54 races with 20 wins, 2 seconds, and 2 thirds.[3] The car qualified for the 1919 Indianapolis 500 but it dropped out after its engine failed.

Are we absolutely sure Miller didn't have a 1985 DeLorean under a tarp in the back of his garage?? That's a pretty modern list of specifications...
hard to see that racing back then, it sure is pretty and pretty different too. that valve system my of been their undooing....toomuch rpm for the piston& rods of the day with that long stroke. and probably not a real good balanced crank/rod/piston assembly either.
