Actually - I do... Stock 351W manifolds from a 91 or 92 motor I'm going to rebuild at some point. Honestly, they look rusted to sh!t right now - but they may clean up nice with some media blasting and paint or ceramic coating. Engine ran when it was pulled so the exhaust manifolds may be mechanically sound - but I'm not 100% sure. (Was pulled from my friend's Dad's truck so I never saw it running. I haven't started tearing the block down and never planned to use the stock manifolds so I haven't looked at them very closely.)
You cover boxing / shipping - and they're yours...I'm happy to send them to you.
