I have a '84 sport coupe swapped with a 350 sbc. Its running electric fans and a cheaper 35gpm electric water pump and water temp runs up to 215. I want to keep it below 200. Mind you this is arizona weather with temps over 100 in the summer. Any water pump or cooling system suggestions?

 

well, living in pheonix, i would never run an electric water pump on anything other than a 1/4 mile only drag type of car.
your car worked just fine stock, try putting some stock stuff back onto it

what type of radiator and fans are you using?

pics help also so we can see what you see

where in az are you?

 

I'm with bk2life on this; don't use an electric water pump on the street.

 

What was the original motor? How old is the radiator? If you jumped up from an iron duke or v6 to the 350 without a rad swap that could be part of the issue too. When my Lemons team did a swap on a 98 f body we found the v6 radiator wasn’t as thick as the v8 unit and the used one we got was full of crap. A quick check on rock auto shows a 20” core for the ol duke while the 305 has 26” cores listed. Just some more food for thought.
