Dave is right, since my original post on this fan subject I have since learned that the SHO fans are smaller and some of the early ones were single speed only I think.
Its hotter'n hell here in Houston this week (100*+ and 50%+ humidity) and I can't wait to try this out. While waiting on the fan I got impatient, so I dropped my TKO to fix a small bearing retainer leak and I dropped my
oil pan to fix a leak there. Now if I can fix this cooling problem, I might actually see how my new Cobra looks with the hood closed.
