You do know that you can simply get a decent 22" rad and it will cool fine and there is no need to go to the 26" one, right?

I think that is best route
On my parts gathering stage I have a 26" with the fan shroud from my other car.
But bought a 22" radiater/shroud that could be rodded out with the right # tanks, but may get a recore job for pieace of mind and think thats the best.
Picked that up along with a mint{looks NOS} 70 compleate jack/hook from Mark Nixon



I've found that many mopar guys are hung up on the 26" rad thing which is weird to me having come from owning many brand X cars. Mopars are 2 row in 22 or 26" widths...many of the GM cars I had had 4 row rads.

I'm sure it has to do with my background on HVAC coils, but I "did the math" before and my recored 22" should cool quite a bit better than a factory 26" rad.

I wouldn't dream of cutting on my #'s 440-6 car's factory 22" rad support so I simply had a high performance 3 row core installed with my original tanks for added cooling but I'm sure the 2 row would have been just fine as it was from the factory.

As far as the original poster's car; if a 22" rad is good enough for a 440-6, I'm sure it will be fine with a 340.
