Engine Running Hot

[taclem]

My stock 292 is running hot, 210 on the road and close to 230-240 in town. I am running a 50/50 mix, I took out my 160 thermostat thinking it may be stuck, now it just takes longer to get hot. I do not have shroud and don't even know it inline sixes used them. I don't feel any cool spots in the radiator and have replaced the cap. I seem to loose anti freeze slowly, I don't see that much out of the overflow tube. No smoke or steam can be seen in the exhaust, and there is not water in the oil. Timing is a little advanced, set for 4500 ft. Any ideas anyone? Can the water pump be pumping too little water? Thanks,
