If this is in the wrong place feel free to move it. I am getting to the point Im going to need a new radiator in my 70 Cutlass Supreme. It does have a 455 in it and I am figuring on an aluminum radiator. Should I go with a 4 core or is 3 enough? Also upgrade to electric fans or stick with stock clutch fan? Any suggestions for radiators would also be appreciated.

Look at Cold Case brand aluminum radiators and also a vendor site Auto City Classic https://www.autocityclassic.com/radiators/

both are quality products that would work with your combo - I currently run the Cold Case and it easily keeps up with Florida heat. Both are 2-core units I believe.

I run it with an HD fan clutch and 7-blade 18" OEM fan (from mid-70's Corvette), along with Milodon high volume water pump.

X2 on Cold case radiators. They are two row but the tubes are 1.250” wide each and they do a great job. If you go with electric fans be prepared to spend some money you are looking at 500.00 plus for fans and controller. A new HD fan clutch is $70.00.

There are plenty of aftermarket aluminum radiators available. Here are two other options.

As mentioned above, if you buy an electric fan from the automotive parts warehouse (Summit or Jegs) be prepared to spend big money. On the other hand, you can find an electric fan in any salvage yard that will work better than any Griffin or Be Cool unit you can buy online.

I have a 2 speed electric fan from a 94 Ford Taurus on my 71 98. It works great. Probably good for 10 or 12 horsepower. Also, I have a dual electric fan from an 01 Ford Windstar on my 86 F250 diesel. Scientifically proven to be good for 10-12 ft. lbs. of torque.
