Thanks for digging into to this. Now I am wondering if moving the fan 1/2 inch inside the shroud with the 2707 fan clutch would make enough of a cooling temp difference to justify the expense.....
Why dont you go with the 2747 (heavy duty) that Desert68 went to? That is about 3/4 inch longer then the one you have now and you did say you needed about an inch more. That would get you real close and would tend to pull more air through, even if your fan blades where sitting 1/4 inch in the shroud, vuce not even sitting in the shroud!
