Getting hot issue
Stock 350 in a 68. Coolant temp. Goes up fast over 55 mph. Old issue, nothing new. 160 thermostat, good tight clutch fan with 7 blade fan. Good shroud. Fan 1/2 in, 1/2 out. Runs 170-180 all day long in city. Say below 55. Goes to 220 and probably would go higher if i let it over 55 mph. 50/50 mix coolant. Just changed radiator cap, of course it won't be that easy. Timing set at 10.5 btdc. 12 is too much. Thoughts ?
