Help on cooling decision
Hello. I need help deciding on how to cool my sons truck we are finishing.
1973 F250 4x4, 390 rebuilt about 300 miles ago.
We put in a summit aluminum radiator with a pair of electric fans that come installed in a shroud.
Radiator: Summit SUM-380428 - Summit Aluminum Racing Radiators - summitracing.com
Fans:
Derale 16927 - Derale High Output Rad Electric Fans - summitracing.com
The temperature is fine while driving (about 180-185), but starts to heat up in traffic, it got to 230 last night. I thought this set up would be more than enough, but it has not even started to get hot here! I am leaning towards trying to put in a taller , 24 high instead of 19, one since I will need to do some modifications due to a 2” body lift.
I do not have any parts, so I would need a new radiator, shroud, and fan assembly if I go that route.
So, I would like words of wisdom. What would you all recommend? I would like to keep it as cost effective as possible, but it MUST work. Thanks in advance!

If you go back to the original setup.
D3TZ8146C .. Fan Shroud ~ Fits: 1968/76 360/390 ~ Used with standard, Xtra cooling and A/C radiators, not used with Super Cooling radiator.
Still available from Ford.
MSRP: $93.30 / ftepartsguy.com: $67.18
The largest radiator Ford supplied for this shroud was used with A/C.
Specs: Heighth: 19 3/4" / Width: 26 1/4" / 2" core thickness / 3 row.
---------------------------------------------------------------------------------------------
The Super Cooling radiator is the way to go, but both it and its fan shroud are very hard to find.
Super Cooling radiators used a different core support, so to install a S/C radiator in a truck that didn't come with one, you have to trim away some metal in your present core support for the radiator to get enough airflow.
S/C radiator specs: Heighth: 24 11/16" / Width: 26 1/4" / 2 5/8" core thickness / 4 row.

I am going by the local Pick and Pull to see what they have. The truck has been a two-year project with my son, frame up, and I would like to stick with new/reman parts as much as possible.
The fans are set to go on at 180, and they turn on between 180-185 by the guage.
I was looking at these:
Radiator, Super Cooling
Fan Shroud, Super Cooling
I know it is a 3 row, and not as thick, but???
Find a fan at the local Pick and Pull and use a clutch?
I am pissed I wasted the $ on the aluminum and fans, we learn by doing.
Trimming, better described as hacking for me, I can do.
ND, I see you are from LA, you must know about sitting in traffic

The top tank on the S/C radiator is almost 6" wide, about 2" wider than the A/C radiator.
S/C radiators were used from 1968 thru 1979. Besides the 360/390's, the 460's used the same one: D3TZ-8005-G.
All Ford fan shrouds are marked on the upper drivers side corner. The mark is molded into the shroud.
S/C radiator shroud: MARKED: D4TA-EB / A/C radiator shroud: MARKED: D3TA-CA (this is the shroud that's still available from Ford).
Sitting in traffic: Not anymore, I'm retired.
I don't venture from the house till 10AM. and am back by 2PM, times which usually avoid the horrid traffic conditions.
btw: I'm in LA County, not the city. It doesn't matter where you live, the traffic is awful no matter where you go.
LA County: 8 million ppl have taken up residence here, and that not counting the estimated 2 MILLION illegals!
LA traffic = IMO, it's not as bad as San Francisco, and compared to Toronto, it's a piece of cake.

best setup i found for cooling is go with a fan clutch and 8 bladed fan, find the fan in a wrecking yard, and use the electric fans as pushers, that works on my jeep and can feel the difference when i switch them on.
