Don,
The radiator is from a 1967 Ford F100 with a small 6 cyl. I cut the side mounts down to fit inside the shell and had the filler relocated so I could access it under the hood. I had it recored locally here with a 3 row Super Cooler (?). At least that's what the guy called it. I haven't had any cooling problems since I installed it. I'm using a 16 inch electric fan pulling air through it. I have a 160 deg. tstat and I've never seen it above 180. It normally stays around 150 to 165. I belive it cost less than $150 for the used radiator and having it recored. Of course the first thing I did was run a 1/4 inch drill through it while I was installing the fan mounts. The fan is mounted solid to the radiator side mounts, not with those squirrelly things that go through the core.
The core size is 18.5 in. by 18.5 in. Top to bottom including cans is 25 in.

The main reason I went with the MTC-1 is that I was building this as a daily driver and I didn't want anything too drastic. At 70 to 80 mph on the freeway it still has enough push to pass without going WOT. That's all I really wanted. I'm going in a different direction with the current project, 1993 Ford Ranger with 460/c6.
This one I want to go.
