I'm asking this on behalf of a friend. He wants to run a carby 750SS motor without the oil cooler (don't ask

).
The diagram in the manual for the engine without an oil cooler shows the connectors blanked off and the feed and return passages connected internally.
Does this passage exist on the motors with an oil cooler but is internally plugged or does the fitment of the hose spigots blank it off? Or is there something else altogether?
Anyone know the answer?
