The DOHC Miller-Goosen-Offenhauser engines have hemispherical combustion chambers.

Why would I replace a brilliant design with a clunky, overweight Mopar push-rod lump?

a nice jet engine?

Maaayybbeee 

Nooo. Better a steam one. Imagine a steam-powered Indy series: the quick pit stops refuelling with coal buckets.
Obviously the cars will need a second crew member as stoker....

Too small, and the larger issue is water consumption rather than fuel consumption.

My Dad was a stationary steam engineer so I know too much about steam power to be able to have the necessary suspension of disbelief for most steam what-ifs.


The vast majority of Steampunk gives me a raging headache, and it's not just in terms of steam power it's also the overuse of brass in place of steel or iron where it wouldn't work for reasons of weight and strength.

Gas turbine power
I do remember a real turbine indy car from way back.

There were quite a few of them actually, but they were legislated out of competition by ever more stringent intake size rules. 

The STP-Paxton being one and the Lotus 56 being another, both of which so nearly won the 500, but both failed through trivial problems while leading the race a few laps from the end.

Parts availability?

It depends on what use your whiff is going to be put to.  Not all whiffs are to make the original design better at its original purpose.
Maybe this is to be used to tow seaplanes out of the water and the Offy didn't have enough bottom end?

Ahhhh there ya go ..knew I remembered one but not the that there was 2 ...cool 😀

I think there were other Indy turbine cars too, but the Paxton and the Lotus 56 were best known as they were both leading the race when they broke down.

There were three Lotus 56s in the '68 race, driven by Graham Hill, Art Pollard and Joe Leonard, the latter being in the lead car when it expired.
