This subject has gotten a lot of attention lately and its basically a personal thing, some guys swear by Griffin, Afco, U.S. Radiator, PRC...etc. Then its the stock fan vs. the electric fan, the pusher vs. the puller fan. Remember the stock fan only turns at Idle rpm when you're sitting in traffic...and thats where you need it the most. Its all a matter of what you can afford and works best for your application. I,m building a '32 Victoria w/ a 331" sbc. I did a lot of homework, asked a lot of questions to car owners and the answers were as varied as the questions. I settled on a PRC alum. rad. (PRCHOTROD.com) built specially for the '32 with a 2750 cfm puller type elec fan (most guys rec.the puller fan). The price was right and the workmanship is xlnt. Send me a pri. email if you want to know more. Good luck...Dave
