How far should the fan stick out of the shroud?

74 Duster
Factory 26" rad & shroud.
7 blade clutch fan (Factory for AC car is think)
I have 2" between the clutch and the radiator core. Is this (see picture) a good spot to run my fan? Can't really come out much, but I could space it in if it would be beneficial.

Usually 1/3 to 1/2 of the fan out of the shroud is best.
Yours looks close enough to not mess with.
