While doing some maintenance I ran the number on the Intake I have 3883948 GM 1. When I looked it, that number comes back to a 396ci. That puts in 66-68 year. I pulled the valve cover and I have 353049 heads the heads are from 70-73. I get that it is not the original block. Does anyone have a clue why someone would run this set up. I get mixing part can improve longevity....... the truck cab I have is a 1980....
