With my 350 I run a Affco aluminum radiator 2 core. I just measured my space went down to a local race car parts store told them what I was doing and the space I had to work with. The radiator I have works great! I also run two 10" electric fans. I think this summer I might put some louvers in the hood just to drop the temp a small amount. Truck runs about 210 in the summer and about 170 in the winter.
