Thanks Tom. I will try your idea of back flushing with radiator upsidedown, also look at thermostat to see if stuck open but 1st I'll try Les Andrews idea of plugging radiator inlet and outlet and then fill radiator to see how much water it takes. He says it should take 1.5 gals and drain in 4 seconds if tubes aren't plugged too much. Thanks again everyone and I will report back but will be a few days.
