Quadrajet interchangeability - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I found a quadrajet that I found on a 1979 Cadillac 425 in my grandfathers garage. I took the carb off, disassembled it and let it soak in degreaser. I once heard that the 1979-1980 quadrajets were the best designed of all the quadrajets. Is this true? I think that the throttle shafts on this carb my be a little worn. Could I put the baseplate of my current (5 year old) quadrajet on the later model body and airhorn? I know that I will have to tinker with the needle and jets also. What do yall think?
