But of course!!!!! (along with the English wheel, planishing hammer, and the rest of the goodies) Hope things go right and I can start putting the shop up next winter!!!!!

As pops said that Spal 16 inch puller is hard to beat. I am also using a "fan controller" from speedway that I can program to turn the fan on and off at various temperatures. the combination of the fan, custom built shroud and controller keep my rod at 180 even in 95 degree heat. Don Jr.

I use a Cooling Component Fan in my 36 Dodge w/ a BB as a pusher ..The best to buy.. Also I use a B&M remote trans cooler under the running board.

Hi Dave,
On the 36 Chevy that I'm building, I put on 2 - 10 inch Spals Puller fans in a shroud. I went with the two fans rather than one larger one because the total surface area calculated to be more with the two fans rather than the one.

A friend pointed out that the shroud should not have any chance for the air to "Leak" around the shroud but rather ONLY pulling it through the radiator. Air, like water, will find the path of least resistance so it is critical there are no gaps on the sides of the shroud. I'm happy in how this turned out cosmetically. The true test is when I get the LT1 fired up and having the computer control the fans on temp range. As the fans are set up at different temp ranges.

My 34 has a 10" pusher on the evaporator in front of the radiator and a spal 16" puller on the rear side of the rad. Temps run 180 - 200 even in 100 degree heat sitting in gridlock traffic. I know a lot of people who talk down on pushers but I have had very good luck with my set up. They are unquestionably noiser than a puller. Only change I might make would be to replace the Spal with a cooling components fax/shroud combo.

My 57 Olds just uses the blade that came with it and it does the job well regardless of heat and traffic.

Wish I could use the mechanical fan that is on the engine, unfortunately just not enough room....

Interesting that the pushers are noisier.....wonder why???? Oh well, looks like it's going to be a 16" puller with the thermostatic control and manual override, owner doesn't want an OEM takeout, guess I'll just order the Spal, looks like a quality unit????

Sure do appreciate the input and the assistance.,

Evolvo; How thick is the fan set up on yours it looks nice and thin.
I've only got about 3.5 inches of clearance between the water
pump and the radiator. Thanks Kurt
