I ended up using a Flex-Light Black Magic 180. It just happens to be the exact width of a 55 radiator and covers 90% of the height. It has a nice solid shroud and has the temp controls and A/C relay. I installed it last night and have a couple more wires to connect before hitting the road. Specs say it pulls 3,000 cfm so that better do the job! It doesn't look as bad as I thought it would.
I'll post some pictures when done.
