[SCOBRAC]

I use a single black magic 150 with great success. The 150 is exactly the size of the Contemporary's fan support and drops in in front of the rack in pinion tube. The fit is awesome and it draws far more air than the AC Delco unit that came on the car. I used a March tensioning rod in stainless for support. It is a great fan. I found the support brackets fexilite included a little cumbersome. If you haven't seen them they would be more at homein a full size pickup... As long as you don't mind the cheepo hot dipped gazvanized look. That's fine. I'm sure it keeps costs down. The all thread supplied is similarly more at home on a Home Depot shelf than a Cobra.

My local sheet metal shop knocked a pair out of .125" 308 stainless on their hydocutter. They look great and are right at home with 12 pt ARP stainless fasteners holding it all in place.

The Black Magic comes stock with a 180-220 degree range of adjustment. I actually prefer it to come on at about 170 so I recalibrated the rheostat, it generally come on at 170-175 Once it kicks on it seems to work flawlessly I made the change in fall but so far it works well without a problem. I had a 180 thermostat in the car before I went to the Black Magic fan. With the original AC Delco fan this meant I was at 195-200 most warm days. Hot days it could see 210 in traffic. That's too hot for my taste on a 40 year old engine running 12:1.

I put a 195 Napa Auto Parts Superstat in this fall when I changed fans. It seems to be opening early. I cant seem to keep the car at 160 on these cool spring mornings (spring has sprung here in California).

I'll let you know what happens as temps increase. I may replace the new thermostat before that. I seems unlikely I'm getting enough conductive cooling (off the block /heads) to keep the temps as low as they have been after an hour on the open road.
