Electric fan for 22" radiator for overheating

[Jim occhiuto]

Has anyone installed an electric fan in addition to the existing clutch fan so as to help with overheating?
I have issues with overheating...22" radiator, clutch fan , no shroud as replaced orig radiator with a 3 row aluminum and old shroud won't fit.

Ant suggestions apprecìated.

Shroud is a big part of cooling. What fan you you have on it? Radiator cap? Thermostat?

Welcome! Many good minds on here to help you out.

Don't have a shroud as I could get a standard shroud that fit on what supposedly was a direct replacement for my 22" radiator.
Measured fan..looks like 17" 7 blade with 8" clutch.

Just changed thermostat from 190 to 160. A little better but still hot. Waiting today for a 16 3000 cfm fan to arrive and hoping that will help.

Other than that I'm at a loss.

When does it overheat? Idle? Cruising at different speeds? Stop and go?

Mostly at idle. It has a decent cam and a 3000 stall converter so it idles high.
Starting to wonder if transmission fluid thru radiator is a contributor

Low air flow at idle. Not big on electric fans but that should fix the idle issue but sometimes they can block airflow at highway speeds.
