Not sure formula 1 but old Grand Prix cars were basically “retired” fighter aircraft engines bolted to a chassis. So probably a rolls engine was used at one point.
by the time there were fighter aircraft (WW1) the GPs were limited to 3 litres, then 2 litres, then 1.5
(the winning 1914 Mercedes 4.5 litre GP engine was studied asap in WW1 by RR and others)
the Vanwall block was cast using the patterns for a RR military 4 cylinder engine (Vandervell asked, RR said yes)
they altered the patterns a bit
RR also designed and made the supercharger etc etc for the V16 BRM
McLaren did their own engine in 1966 F1
a 4.2 litre Indy Ford dohc V8 destroked to 3 litres by Stellite spraying new big end journals
hugely over-ported and over-valved it went slightly better when they used smaller inlet tracts (ex Chrysler)
so got a point at Monte Carlo
Brabham modified road car (215 Oldsmobile) pushrod ohv V8 aluminium blocks to win ....
1966 and 1967 F1 WDCs and WCCs (after a while they cast the blocks themselves)
Aston Martin made an F1 car and engine
