I just swapped out the 4 bolt water pump and timing cover for an 8 bolt on my 62. Before it ran at 195-200 cruising with a 160 stat, hit 205-210 at idle. After the swap, I had to switch to a 180 stat because it wouldn't get over 170 at idle, with ambient temps in the pow 90s. I'm finishing my AC install, that will be the real test. I have an aluminum radiator already, and a 6 blade fan with clutch.
