360 swap manifolds ?s

Yes, those are the small hole manifolds. Mopar made manifolds for magnum engines for many years but only certain manifoldS in certain years had the very large hole. These large hole manifolds aren't quite as large as the 340 but after I "machine" them they are as large or larger than the 340 making them the only other cast manifold that flows anywhere close to the big 340 manifold.

Do you know how much can be hogged out of the 273 manifold? Doesn't seem like much if any at all but I need to use it until I can figure somethin else out with these other manifolds. So id like to just do the best I can with what I have for right now. I know some people have talked about extrude honing the manifold but that seems like a expensive band aid and not a real solution. If I was running a 273 it would be more viable but I don't think there will ever be enough hogging of that manifold to get it anywhere near the stock 360 manifolds.
