442 Exhaust Manifold

Greetings--

Looking for RH exhaust manifold, casting number 402294--ID "Z." Any information on the repros would be appreciated as well. After spinning a couple rod bearings, I'm having the 455 rebuilt and just found out from my mechanic that the manifold is cracked. Feel free to email me at fkheinrich@yahoo.com Thanks!

You might want to look into having the manifold repaired. A good welding shop should be able to weld up any crack in a cast iron manifold. I had the manifolds on my 394 repaired and one of them had a 5 inch crack in it. After driving it for years and years the weld is holding strong.

Or, if you just have to buy a new one you can check out the following website. They make reproductions of the W and Z manifolds.
