I have a 1993 SS truck that will getting a motor/trans upgrade soon. I am looking to for a new radiator with electric fans to keep everything cool.
Who make the best radiator for this set up?
Thanks in advance.

Agreed, I usually try to use the upgraded GM designed stuff myself. I have not had good luck with electric fans keeping an engine cool here in Texas. The clutch fan does better. The L31 I just built, probably a bit under 400 hp has a 454 spec radiator for a 1988-1991 G30 van, 4.3L 11 bladed S10 fan that fits in the OE 1987 G20 shroud nicely and a heavy duty tow package L31 350 fan clutch. I did not go with a severe duty on this one because I doubt it will tow anything. Even still I did add GMT400 replacement oil cooler lines to it to help keep the idle oil pressure up at hot idle. I have had it running with this setup, in 70F temps the fan mostly freewheels, when the engine gets up around 190F, you can hear the fan speed up for 30-60 seconds and the resulting surge in airflow, then it releases with the coolant down at the thermostats 178-180F closing point. With a properly functioning thermostatic fan clutch, it only runs the fan enough to keep it under the fans 190-200F set point.Greetings RCC1, and welcome to the GMT400 forum!
Listen, there's a group of fellow Texans who have
figured out what it takes to keep their hard-charging
engines cool. @454cid's comments in reply #4 are spot on.
And if you were to search this site for discussions about
cooling system upgrades, members like @L31MaxExpress
do a great job of describing their tested-good setups in
detail, both before & after.
My advice? Don't let all the marketeering surrounding
aftermarket cooling fans lead you to throwing away all
the solid cooling engineering that GM originally built into
these vehicles from the experience they gained through
testing at the Arizona Desert Proving Grounds.

Or if you do deviate from what the factory came up with,
have a solid reason for doing so. By the way, sounds like
a nice truck that you are working with. Don't be bashful
sharing a photo or two.
Keep it cool!
