Hi guys Im wondering what radiator and fan combos you guys are using for best results on cooling and also fitment. I moved the front shelf forward already and the engine will be mounted based on the fast cars front engine engine mounts. Whats the largest I could fit without frame modifications?

Best I have found is the ACP FM-ER209. Large 64-66 Mustang with 302. Just fits between the chassis rails without cutting into them. All alloy and 2 large rows of 1.25" tubes. Needs minor trimming of the mounting tabs and you will need to fab up some mounts. Depending on your year of car you may need weld in the two side radiator panels or fab you own. Nice thing with the Mustang rads are they will always be available and they are inexpensive compared to others. Volvo fans come highly recommended.

If you are willing to cut into the frame rails (yes I know its a uni-body car), Eastwood Company 19x22 triflow rad is possible and also inexpensive. Core is only 1" larger than the ACP rad though!
