Hello,I'm in need of a decent radiator for my 1966 oldsmobile f85.It has 330 engine along with a/c and heat that's why I would like a four core radiator.Thanks.

 

I had my original 3 row radiator recorded with a high efficiency 4 row at a local radiator shop and it keeps my engine cool during the 110+ Phoenix summers with the AC on.
The core was made by Craig but I don't have the part number now as I'm traveling. If you need it I can post it when I get home, or you can try searching for one of my earlier posts with the info.

 

I bought this aluminum radiator from Auto Zone part number 433840 $120.00 it drops right in a 67- its for a Suburban-or C-10. Double check but I think 66-67 core supports are the same. Then you need two hose reducers from NAPA 900 and 901, there like 3.00 each. My 455 stays at 150-180 degrees in Texas heat. I'm assuming you have the 2 speed Jet-away trans-you will need to reroute your cooler lines, Mines a M-21 4-speed. If your going original scratch the idea.

 

Check these folks out. Order the high efficiency core, original look and fit with better than aluminum performance.

I checked my records and the shop rebuilt my radiator using a Craig 858384 high efficiency core and my original end tanks.
