The fan should be centered in the shroud with a minimum of a 1/2 inch gap evenly spaced all the way around. With a 2 inch gap at the top you either have the wrong shroud (most likely) or the engine is mounted too low. The 2 inch gap is what's causing your overheating problem.

Also a Hayden 2731 clutch is 0.61 inches longer than the 2747. Other than the length both clutches are identical.
