im gonna buy a new radiator, I just need to find one with correct outlets.
You need the the 1973 and up 22" Valiant etc. Get the regular 3 row. That's the year I had to use on my in my 5.9 Magnum swap. It was a slant 6 car, too. The slant six radiator covers 6' or so of the 22 inch opening. You can see my lower hose is on the passenger side. I did have to tell them to delete the 1+ inch hole for the bung that held a sensor on the passenger side top tank. My four core is the regular core, because it flows more air once an A/C condenser is put in front of it.
Call US Radiator, tell them what you have and get one of the best made units on the market that looks stock. If you search their website, you will see all the various outlet configurations. they will tell you which core to run.
Important!!! When you put which ever radiator you end up buying in your car, run a small cup shaped piece of moderately heavy hardware cloth screen with the bottom of the cone shaped screen pointing inside the top radiator opening. Leave enough hardware cloth sticking out to wrap over the inlet, then slide your radiator hose over it and clamp it up. Drive the car for a day and then clean the screen again. Do this for several days, or until the screen remains clean. This will catch a lot of the junk in your cooling system that would otherwise flow around while your driving and plug your new radiator down tubes up FOREVER.
Back flush the motor with the thermostat out from both directions, upper and lower hose. Also do the same thing to your heater core. Remove both hoses and flush in both directions with full garden hose pressure.
What motor do you have in it again? Never mind, I reread your post. Are you running a shroud? The 73 through 76 22" shrouds are almost impossible to find. Good luck there!
I haven't found on yet, and am now going to attempt to make a decent looking one out of sheetmetal, because I'm adding a stroker motor and putting a big A/C condenser in front of it along with a trans cooler. I always try my best to seal every side/ top and bottom opening up so nearly 100% of the air in front of the car has to pass through the condenser and radiator.
