Inliners International Forums General Discussion Engines Swapping a 250 for a 292 exhaust manifold

They are both exactly the same except the 77 2.25 inch hole has 3 bolt and the 74 2.25 inch hole has 2 bolt and a shield for the stove and two/metal choke wire wrapped up liike a coil on it to control the stove. With an opening for pipe to go to the air cleaner.

77's wire is not there anymore and may be why we need a new manifold.

They are on the drivers side angled at about 5 o'clock when looking at it from the drivers side. The exhaust pipe meets it and a foot or two make 130 degrees tunr and then straighten out, all on driver side.

Will the exhaust hardware from 12-bolt not work?

**Edit***
Well like I said I am not a mechanic but this muffler and brake shop in my neighborhood sold me a coluple flanges that may do the trick but they are 2 inchs but they fir the manifold but look a little small for the donut.

Thanks to everyone I hope to get working on it tomorrow after a quick trip to return this spilt flange that didn't fit the bolt holes.
