Tired of my wagon heating with the air conditioning running. Looking for recommendations for a cross flow radiator with air conditioning condenser for my 55 Chevy Handyman wagon. The wagon has a 327 stock engine and turbo 350 trans with power steering. I am running a Griffith aluminum radiator in the V8 position. I want to run the cross flow, a large metal fan with a shroud.

Does your existing Griffin aluminum have a fan shroud? or a electric fan? .Mine has both and I have absolutely 0 problems with over heating. I suspect some other problems.

Is your radiator mounted in the V8 position or the 6 cyl position? I run a 327, 700R4 and A/C and have no problems with an aluminum vertical flow radiator mounted in the 6cyl position with two Spal fans with a shroud. It never even gets close to overheating. I live in Texas and it gets hot here!
I recommend moving your existing radiator to the 6 cyl position if it is not already there and adding electric fans with a shroud as mentioned above.

Same advice from me as the other folks here. The current radiator is probably not your first solution.
Check that the engine timing is set properly (to ensure the engine is running at optimum advance), and look into a kit that contains electric fans mounted into a shroud that will fit on your radiator. Also one that contains an electronic fan controller that you can set for on and off temps (based on the reading coming from your coolant sending unit). Spal probably makes a kit for all of this.

But if you really want to spend more money for solutions, then consider one of these all in one cross flow radiator, condensor, fans, core support setups like this one on eBay

A radiator with 2, 1.25"tubes will out cool just about everything.
I also like two fans with a shroud in case one of them quits working.

Hey Larry,
What cfm are the fans you are using?

I am using two of these fans: https://the-fan-man.com/product/11-spal-pull- type-... They are rated at 1390 cfm. They might actually be a bit overkill for my use. On cool days the car struggles to get to 180 degrees, but on hot days with the A/C going full blast, 180 degrees!. I have a 180 degree thermostat. I made my own shroud for them. I didn't mean to post the photos twice but did not know how to delete the extras. If you shop around on the internet, you will find better prices than what I shown here. Amazon sell Spal fans.

The dual fan setup is the way to go. I am not enamored by the noise that dual fans can create.
I have 2 cars that use a 3 relay system that turns both fans at half speed, then if needed will switch both fans to full speed. Mine very rarely runs the fans at full speed, and sounds much less annoying.
I believe that the wiring schematic is posted online here somewhere. If not, I can do it, if requested.

I saw this recently:
https://www.summitracing.com/parts/rad-cht56357ls

I've had a Griffin 6-cyl position aluminum radiator since 1998 with a 16" puller fan. First ran it with a 396, currently with a 403 LS. I don't have AC, though. The Griffin developed a leak, so I went to a Cold Case radiator 6-cyl position with built-in shroud and 16" puller fan.

I just got it buttoned up a couple of days ago. So far all I can say is it keeps the engine cool idling in the garage like the Griffin never could.

1957 Bel Air 4-door sedan. Owned since 12/71. 403 LS, 823 heads, Manley guts, Bullet cam, Hedman 1-7/8" hedders. 4L80E with 4000 stall lock-up converter. FiTech EFI. 3" dual X-pipe Magnaflow. 9" with 3.89:1 locker. Street/strip car.
