Thanx It is the triple flo Desert Cooler copper/brass and it very tight compared wit the stock Radiator. I figured that would give it more surface area but now that you mention it air flow might be more of a problem. Anyway im stuck with it now and it took 3 times to get them to make one correctly so I don't want to do that again. It has the recommended 7 lb cap. I'm going to recheck the timing. I used a vacume guage and turned max vac 20 and backed to 17, new vac adv. rebuilt carb. New everything!!! RUNS GREAT!!! How do I check to see if it is running to lean at idle? How muck fuel press is required for the rochester (new AC vac assist fuel pump)
thanx Ton
