Does anyone know where to get an electric fan and shroud for my 1938 (with 292ci) ? Same size rad as original.. 16x20 coverage .. Looking for a univeral maybe that wont be $$$$$$$$$
To add:
A. The fan is on the outside of the rad, not on the engine side because of space.
B. I dont know if that makes it a push or pull.. I think its a push though
C. Do such fans NEED a shroud? A shroud would seem to block air.. Does it create hot spots without a shroud?
D. Any suggestions for cfm?
Thank guys.

Get the largest aluminum 3-4 row radiator that will bolt in place and then the largest cfm pusher electric fan that will mount in front of it. Evilbay and a tape measure are your best friends. Good luck.

There needs to be room for air to get through the core when out on the road. At highway speeds you could turn the fan off and likely still cool the engine just fine. With a full shroud, that won't happen! You may have room on the sides for the fan to hang over, this will allow even bigger diameter and more CFM. | | | | | Joined: Jan 2013 Posts: 2,237 Moderator: Interiors, Texas Bolters, Name that Part | | Moderator: Interiors, Texas Bolters, Name that Part Joined: Jan 2013 Posts: 2,237 | I just bought a pusher fan from jegs.com that was cheap and has 2300 cfm I think for my 51 with 261 in it. Depends if you want a slim one or not.

Brushless in my opinion is better. Over the last 40 years, I've dissected probably 40 brushless fans to determine why they fail and about 20 brushed fans for the same reason. If anyone here wants that information, I'm happy to share. Just let me know.
