66 Cuda Radiator

My son's 65 Cuda with a 375 HP 340 uses a 22" 3 row AL rad. Cools OK on the interstate at 70-80 MPH at 80F outside.... which is no where near to using 375 HP BTW! The fan set up is going to be critical for the smaller 22' rad versus a later 26" rad.

How much HP in your 360 and what is it used for? Full time drag racing? Going to the grocery store?
