'72 Dart w/360 cooling issues

Hey Guys....still trying to figure out my '72, I added a electric fan (3100 cfm) and most likely need more amps from alternator, I think the stock is 45amps...the new fan pulls 19 amps. So if I go with say a 60 to 65 amp alternator would that do it? seems logical. Also will stock wiring handle the difference in amps? I do have an aluminum rad.

My set up; 360 bored 20 over with TRW 10.5 to 1 , 509/292 cam, single plane with 750 holley, steal heads, 727 with coan 3500 stall, 410 Dana with spool.

I like to do local cruises and at the end of last season while running 60 to 65 mph (to get downtown) the car ran between 210 and 220. it did cool to 190 to 200 when off interstate.

Hope this is enough info.... what are you guys running to keep cool? Anyone have a similar set up?
