i have not been on for awhile,i am doing the same project you are,
lets talk

a two row radiator will cool a 350 without any problems as long as you are not running air conditioning. If you have ac, you need a 3 row core or you could have a 2 row built with 18 fins per inch instead of the standard 12 fpi

Ive got a 72 with the stock radiator. It has a 355 in it and I was having overheating problems. I put a new therostat in it, a better flex fan, high volume water pump, fabricated my own diamondplate fan shroud, cut out the fender wells and have no problems with overhating anymore. Im about to put on header wrap which I highly suggest. Hope any of this helps!
