Radiator that will fit my 64 barracuda for a 340 upgrade

OK I measured the 1964-1/2.
The Champion MC64DT radiator dimensions appear to be correct for my 1964-1/2 white/gold 340 mild cam 3.91 gears push button auto barracuda except the top inlet would have to be moved to the driver's side because of my aftermarket AC. Ledfoot racing will sell me the radiator and move the top inlet for an $80.00 fee. 3 week lead time. Once modified No Returns.
OK here is my last radiator question...
2 row, 3 row, or 4 row?
If I read online on aluminum radiators...
some articles say 2 row 1 x 2 = 2.00" cooling area, vs. 3 row .62 x 3 = 1.86" cooling area, with the same row spacing and cooling fins.
some articles say 3 row are better, in the above case 2 row seems better.
But if the row spacing is closer and there's more cooling fins in between the rows, now its messy since row spacing fin design is not usually listed.
The MC64DT also has a 4 row option .62 x 4 = 2.48" cooling area
Pricing$
64CT: 2 row $270 + $80= $350
64CT: 3 row $275 + $80= $355
64CT: 4 row $350 + $80= $430 up to 650hp. [I doubt mine will be much more than 350Hp]

OK chime in guys... Angelo aka Guido
