install a shoul like the picture your posting ?


A shroud will definitely help. I have been running my Jeep/5.0 for 3 years without a shroud, but when I tear it down to put a fresh engine in it (its really getting tired) I am going to add a bigger fan and a shroud.

You mention Absolute Radiator. I have one of theirs sitting waiting to go in the '39 Dodge. Looks like a nice piece, and I'm anxious to see how it cools the 394. The picture I posted is the one my Son had built for his '29 Sedan with 455 Olds. I don't remember who built it, (we ran into them at Turkey Run last fall) but it is a work of art. Like I mentioned, he was worried about cooling that engine here in Florida, and they told him they use that very same radiator in the 800 HP blown Willys.

Like 49willysSD said, sometimes you have to use a pusher, or even two, because of space limitations. I would have used a couple in the Jeep (because the darned 5.0 is so close to the radiator) but the grille is right up against the front of the radiator. I finally went to a very slim fan, but had to give up CFM's because they have a smaller motor on them.

Finally, if you can, use a SPAL brand fan. From previous posts on this forum, the general consensus is that they are the best, air-flow-wise. I also heard that from the guy at Turkey Run. He says he continually tests every fan that comes along, and none have matched Spal for doing what they claim.

I HATE sitting at red lights and seeing that needle climb, so we are really overengineering the cooling system in the two cars we are currently building.

JMO,
