Correct, but be aware of what you are buying. Here are examples of the kits. The BE Cool kit is the best user friendly. I have the BE Cool kit installed on my 1967 Camaro with no problems in 3yrs. Compare - SummitRacing.com

OneMoreTime Good shrouding is absolutely needed as a lot of cooling issues come from lack of airflow to the radiator and also allowing for evacuation of hot air from the engine compartment..You may spend a lot of time designing and fabricating the radiator shroud..

bigdog7373 It would be a good idea to use a shroud too. What size fan is it?

Still not the whole story. Centrifugal fans (the ones with a clutch in them) do slow down at speed but a true mechanical fan is solidily bolted to the water pump.

A thermostatically controlled fan should keep you cool. You can always install 2 of them with higher capacity later if you need it.

Not true at all. Mechanical fans stop spinning while at cruising speed. Running an electric fan all the time will use more power than a mechanical fan because of the elctrical draw on the alternator

bigdog7373 Yes, lots of guys run an electric fan only. Get a temperature controller though, do depend on yourself turning of a toggle switch like some guys do.

Cooling question

I am building a tube chassis, sbc 350, 700R4, narrowed 9' Ford rear 1969 VW Squareback station wagon. I will also be running A/C. Question I have is this. I have a new aluminum radiator (fits 78-80 Camaro) with an electric fan/shroud that puts out 1800 CFM The car will probably weigh in at about 2,500 pounds. My question is. Can I just ran this fan only, without a water pump fan? Mainly due to room restrictions.
