Best to go with the factory proven HD cooling system. Seven blade fan with clutch, shroud, and 26" radiator and you can't go wrong.

@moparlee just nailed it. Cheapest and easiest way to do what you what to do.

You can do a 22" triple high efficiency rad give you have the 22" opening but you still want a 17" clutch fan + shroud

sounds good . i have to measure my opening on my radiator support next visit to body shop . hopefully tonight or tomorrow. if i can use a 26 is a two core ok ?

Since your car was a non A/C car the radiator opening will only fit a 22" radiator and if you did want to fit a 26" radiator, you will loose 2" of cooling per side. I would do like Chryco Psycho said and buy a good 22" radiator.

Or modify the firewall for 26" , the part is available

Since your car is painted and you may not want to modify the radiator passenger panel, a good two row aluminum radiator will be fine. Make sure you get a fan shroud, that's a big part of the cooling.

All of my classic cars are factory cooling systems with no issues unless I get stuck in something like the Woodward Dream cruise which can take hours to get a mile. The temps will definitely creep up. However, my blue Challenger makes more than double the horsepower of my more stock-ish with a custom made aluminum radiator with dual electric Derale electric fans and it runs cooler than all of my other cars all day long.
