I agree with all that has been said.

Yes, run only a puller behind, 16 inch is good.

A shroud is very important, and easy to make up out of either aluminum stock or sheet steel (18-20 gauge), it should cover the entire finned area so air is drawn across the entire core when the fan is pulling.

I agree also that SPAL fans are very efficient. My Jeep/5.0 ran warm until I put a SPAL on it, never had a problem after that.

Here is how we fabbed up one shroud.........nothing more than a square pizza pan with a 16 inch hole in the middle.

btsave,
I'm glad you found your problem, and that it was not a cooling/over heating problem!

btsave,
"Spoke to the Radiator shop again, what he meant (He's Cuban so his English was limited.) by "too much pressure" was that the radiator itself was mounted to tightly to the frame and hood! When the body flexes, there's stress on the radiator which is why the seem split after I damaged the right fender in the blow out! In a normal sized radiator, such as in modern cars, it's not such an issue, he said, but with one as big as this, with an X-frame, it's an issue. I looked at the mount and will be adding some rubber pads and spring bolts to eliminate any problems in the future."

If it's running at 180, and it doesn't look bad, I'd leave the fans the way the are. After all, 180 is normal temp to run at! The only reason to change it would be for looks, and only if it looks bad to you!!!

Running two pusher fans is not doing it wrong, it's just not the way "some" people do it.

Save the $400.00 plus and put the time and money else where.

Just some FYI for anyone who is going to use and electric fan.
Do not buy a fan that says to reverse the blades and that will make it a "pusher".....it won't........I know for sure Spal does make a true pusher or puller fan. There may be some others now on the market that do have either or, but I know for a fact Spal does.
I had used a Spal pusher on my pro street car and it worked very well.
