un furtunatly, there is not a direct replacement for the 470. The 4.3 V6 is the most common replaceemnt for the 470, but it will require building up motor mounts to the stringers. Its not that big of a job. Depending on which drive/transom plate you have( 82 was a change over year) you may not have to change anything on it to install a complete V6 engine. None of the accesories on the 470 will work on the V6, so you will have to get a complete engine. The biggest issue with the V6 is cost, some times its not that much more to put a V8 in there instead, its not that much weight difference, and it flat haul butt with a V8. I poersonally like the 470, but parts are getting harder and harder to find for them. What caused the head gasket to go( they don't blow out for no reason)
