I am unsuccessful in finding a 18" 7 blade fan for a '69, 350, no air, std shift. What other fan will interchange with this and fit a std. shroud? Tks for any help.

I'm running this...http://www.flex-a-lite.com/auto/html/7-blade-flex.html It pulls a lot of air and I have a 4 core big block radiator with a small block a.c. shroud. Cools my 406 sb just fine. Some would say a clutch fan is better but I had one fall apart once (hence the new big block 4 core radiator). Maybe I just had a cheap clutch. I don't see over 6300 rpm.

Thanks for the assistance. I'll check into it.
