Late model marine manifolds for a 350 sbc engine, no cracks was working when I took them off, no problems with them. Real nice set of manifolds. 350 with omc outboard over drive, these things are a bit heavy,I would prefer local pickup, but I will assist in shipping. For $45 to put on a crate strapped down will take to a carrier, would prefer to use R AND L CARRIERS, Use them a lot there the cheapest rates I have found, they also come by my shop everyday. They do need to be put on a pallet because they are heavy they will not work in a cardboard box, will send a bill of Laiding, buyer pays for shipping cost. Ask questions please ask, sold the boat, put motor in my hot rod, do not need manifolds no more. They are a very good set of manifolds, these things are extremely expensive, these manifolds fits a variety of motor boats. Any questions please ask before bidding, they have been pressure tested. Thanks for looking.
