Here is my preliminary mock-up. Very, very tight. But it will fit. I gain a good amount of distance between the pump and fan by angling the bottom of the radiator to the front of the car by 3/4" or so. It really needs the room. Does anyone see a problem with that? It doesn't look too bad.

I just got my Champion radiator. It's twisted. But not too much to use. Besides, I am cutting off the radiator's mounting brackets and opening up the radiator harness so I can stick the rad though the radiator harness. Then I will weld the bracketes back on.

I will also have to mount the fan against the rad (with a little foam tape for cushion) instead of on the shroud mounts. I didn't have the space to spare.

I would like to thank Feets and all the other posters here for this thread. I have learned so much here.
