Best AMC Radiator?

A better fitting shroud would definitely help. Unless you're getting top notch (rather pricey!) aftermarket fans like Spal or Derale, it's a crap shoot. Most of the cheaper fans have cfm ratings in "clear air" -- nothing in front of them. So it will pull 1200 cfm (or whatever, just pulling a number out of my... hat) for sure, but stick it in front of something that resists air flow (like a radiator!) and it may only pull half that much. I tried a pair of 12" aftermarket fans and they would cool my hopped up 4.0L fine -- until the AC was turned on without outside temps over 90. Could run AC going down the road, but after 10 minutes of low speed (under about 45) driving the temp would start to rise -- only 2-3 minutes sitting in traffic. Once engine temp reached 230 I cut the AC off, and it would take 15 minutes of highway driving to get it back down to 200 (195 stat). It wouldn't drop much if sitting in traffic, but wouldn't get hotter. Switched to a Contour fan and I can now run AC at any time! OEM fans and replacements (a new aftermarket 95-00 Contour V6 replacement dual fan/shroud is under $125!!) work so much better than aftermarket fans. I have both my fans running wide open all the time. I need to step the thermostats to run them at half speed (Contour setup uses a big resistor to drop voltage -- not included with replacement fans) and kick up at say 210. They are a bit loud running high speed all the time -- most noticeable when the engine shuts off and fans are still running until thermo switch cools (2-5 minutes).

I just bought  Cold Case RAD-AMC100AK from Summit for my 68 Jav 343, it comes with 2 electric fans which I am going to run off my sniper EFI.
