Radiator Fan Options For a 1926 Ford Street Rod With 355 Chevy Small Block

Question:

Hi. This fan would go on a 1926 Model Ford street rod with a Chevy 355 cu. in. motor. I would prefer 17inch electric but only have 2inch clearance from the fan hub to the radiator. Have anything that would fit? Otherwise, what are the CFMs of this fan at idle of app. 700rpms to 1000rpms? When it idles running at car shows the temperature has a tendency to climb up. Looking for a solution. Thanks

You may be able to use the Lo-Profile 12-1/8" Dual Electric Radiator Fan # FLX410 on your 1926 Ford Street Rod. The dual fans are capable of pulling 2,500 cubic foot of air per minute. The dual fan setup also gives you a smaller profile and offsets the high points of the motors. The entire setup is 26-1/4" wide, 15-1/2" tall and 2-5/8" deep at the tallest point. You will need to measure your exact setup to determine if they will fit with your fan hub only being 2" from the radiator.

The Derale 17" Stainless Steel Flex Fan # D19717 is not rated by Derale for CFM's. This is due to the fans not having the same speed on every engine like you get with electric fans.
