Radiator size

[MeMopar]

hope you guys can help me out with this doubt:
Currently, and because it was the car cane with, I have a 22 x 22 x 2.5 radiator which seems to be more suitable in a /6 engine. However, I managed to buy a 26 x 22 x 2 radiator which came from a duster. Question is: will the 22x22 be enough for cooling my engine? Motor is a mild modified 360.

Thanks

Your factory radiator should be adequate . Your 26" radiator won't fit without surgery , i.e. hacking up your core support . My Scamp has a 22" radiator for a v8 with A/C which is the same as a 340 with no A/C . My 22" is now cooling a 383 . Try the 22", no harm , no foul .
