i searched but i can't find what year fans people are using...i thought it was early to mid 90's fans...am i wrong???

1998.

rockauto.com has very good prices.

So what is needed with this. Fan motor and fan assembly? Is this the best fan to take away heat? Or is the older mustang ones better. I want to have the best possible? What kind of CFM does the Mark move? I have 2 12 inch fans now thats supposed to move 1650cfm each and not sure if its cutting it or not.
Does the Mark fans require any more alternator or anything.
Sorry for so many ???

I looked on the rockauto site, shows 156 for fan assem. and 156 for the motor.

The fan and motor are an assembly. That's the only way they come. The part on rockauto.com is a Ford OE part. $156 for the asssembly is about right.

The Mark VIII fan moves more air than just about any other fan arrangement. It draws 35 amps while running at full speed, and spikes higher when turning on. A high amperage rated relay is required.

If you use a DC Controls progressive speed controller you may be able to get away with a smaller alternator.

There is info on the fan and controller on my website.

Not sure what you mean aperage relay is required...LOL Sorry, I am ordering one of these fans for my car thurs and want to make sure that the shop doing it will have all the tools they need to complete it. I only want to run the fan at full speed all the time. I really like to get my temps to the 190s.
Thanks,

PS if I need a new alternator anyone know where I can get one. The current one I have is small (very small belt) and is chrome.

Running that fan all the time will cause the water temperatures to be too cold it the rest of the cooling system is properly sized. Using an in-engine temperature switch with a 195on/185off will do what you need, not overcool, and prevent premature fan failure.

The engine temperature switch is a low power device. It must be used together with a high-amp rated relay to power the fan.

You may want to start a seperate topic for your alternator needs.
