I don't know the answer, but what source reference books would have these casting numbers? I can post them on the 62-65 site if located. Thanks, Gary H. -----Original Message----- >I have a set of max wedge exhaust manifolds that I'm trying to decode. One has what appears to be a casting date of K62 which I believe decodes to Nov 62. The other has what appears to have a date code of K152. That one has thrown me for a loop. Can any of the MW experts out there please give me a hand? Is that K152 a date code or something else? Both manifolds also have a casting mark of N2. What does that mean? > >Dave ---- Please address private mail -- mail of interest to only one person -- directly to that person.
