Installed the 6 blade HD steel fan with fixed blades. It made a difference right away! Car ran tonite at 175*, never went over 185* at idle or stop lites. Will have to test during the day to see how it is in the heat, but it is looking good. Planning on checking curve in distributor and carb jetting to get it really dailed in. May even get a thinner spacer to bring the fan back 1/2" more to increase air flow. Many thanks to all who took the time to share their thoughts. I'll keep you posted. Tom
