The super-fuels the engineers wanted would probably have added even more. The placement of the valves also means that the combustion chamber has a smaller surface area and thus greater thermal efficiency some 20% better than a comparable flathead. But it DID have a fairly illustrious season on the track and in road racing. Deciding Burrells ideas had promise, Wolfram and Skinner organized a new advance design group to develop a new overhead-valve (OHV) V8 engine and assigned Burrell to lead it.

The practice of keeping model names alive even though applied to a vehicle with little in common with the original seems to annoy no one but me, [example Impala], why not keep division names alive and apply them to selected models. Neither of GMs new OHV V8s had an exceptionally high compression ratio at first Oldsmobiles was 7.25:1, Cadillacs 7.5:1 but that was mostly a reflection of the low octane of the gasoline of the time.
