Personally I would spring for the 4 row aluminum radiator now while your doing some upgrades. Many on here think the 4 row is overkill but my 450hp 350 ‘62 C-10 runs 180 day in day out in Oklahoma summers and winters. No worries and since I bought a ‘62 specific radiator, it mounted up in less than 30 minutes. If your going to add AC later your truck will thank you for the upgrade. JMO
