Can anyone decode a set of exhaust manifolds for me ? I was offered a set of "big block" manifolds with the following numbers; 3751071 and 3751068. I believe they are 72-74 or so BB Charger manifolds. I have not seen them yet, so cannot describe them . Guy says they look like the HP from 68-71. They have to be better than the 78 truck manifolds I have now. Anybody know for sure what these are ? Can you post pix ? Really appreciate this help, Don.
