I'm happy as a Pig in Shiot

Heres the skinny filled my block uo with Viniger and water let sit for 2 weeks drain it all out, Brown as hell, did several more washes, Installed my Big NEW 1942 ford truck rad (Aluminium) in stalled a NOS 7 blade aluminum fan blade ,(fit like a glove) new hoses etc, just filled with water and no thermos. Ran the motor for 1 hr today in 85 degree weather in the sun , Temp stayed at 126 degree reved it up temp rose to 135 degree then dropped. that blade sucked more in at idle i could feel my cloths being sucked in and blew so much air thru the motor that it barely got hot and Blow that it Did. Is this Ok running to cool? I'm happy Very Happy with the results . Cheers BIG MIKE
