Classic/Antique Car Repair: 1964 Chevy Chevelle Malibu, griffin aluminum radiator, chevelle malibu

Question
I have a 64 with a 350.  I just replaced the radiator with a Griffin aluminum
radiator. The car runs between 190-200 at speed.  Is that ok or should I invest
in some electric fans to cool?  

Answer
GREG hi; I think it is a little hi for a alum. rad. but how close is the fan to the rad, also do you have a schroud on it. also a flex fan w/ clutch would help. and how is the rad cap. also how are the hoses , some times the top hose if not a flex hose can suck itself closed and get you hot, and how is the thermastadt. put in a 160 .
