I was thinking VW, but I haven't worked on aircooled VWs since the early
One that would come in was a dragster, around 200 hp that didn't have
anything installed if it didn't provide power. Including the cooling system.
It only had to run for a minute or two at a time :-)

Air cooled VWs had different timing on the #3 cylinder. The oil cooler sat
on top of #3 so it naturally ran hotter. 
By playing with the cam and ignition timing they tried to get it to create
less heat in that cylinder. 
This is why AC VWs have such an odd sounding idle.
