Alternator and electric radiator fan upgrade

I have a 1967 289 automatic and the stock radiator and belt fan aren't cooling enough. The radiator has been rebuilt and I have an external trans cooler. I want to add a sound system and air conditioning in the future so I know I need a new alternator but I'm not sure how many Amps. I would like to swap to an electric fan but I'm not sure if that is going to be enough for traffic jams which leads me to a few questions. Is there a car I can pull an alternator, fan and shroud assembly from at the junk yard? Is this all just lipstick on a pig without a new radiator? If I get the radiator should I use the transmission section or stick to my external?

Well if you are going to add AC then you need to upgrade the radiator. Factory equipped AC cars had the 24" radiator instead of the regular 20". As far as alternator, do a 3G swap. Its easy and a very good upgrade. I had an electric fan and it did pretty good, even here in Texas. Just make sure you have a good thermostat (180*).

I just installed a new radiator/fan combo from Mustangs to fear. It is a bit pricey but my car run much cooler with it, plus it looks alot better.

I've seen a few write ups where people have converted the radiator and electric fans out of a late model taurus to fit in our cars.

I am currently running a V belt and my alternator guy says i should upgrade to a serpentine belt since I'm trying to get to 135 amps. Is there a bracket and pulley i can use in place of the AC to hook up my serpentine? The 3G alternator he recommended to me has a different body then the stock one and needs a bracket to fit my 289 but he couldn't tell me where to get a bracket. Should I go with a 1 wire or 3 wire?

You don't need a serpentine belt to run a 3G. I have a 3G as well as as few others. I have a CVF racing bracket and pulley.

A 3G can bolt in place of the factory alternator.

Here is a 3G on my car:

I'm currently running a 3g with the CVF racing bracket and pulleys as well. I used the PA performance conversion kit for the wiring piece.

It is also poplular to use the fan and shroud assembly out of a 2000 ish Ford contour. They fit straight on most 24" radiators. This is also the route I will be going.
