318 manifolds to 360?

tbr3 said

Hi Guys,

Does anyone know if 318 manifolds are the same as 360? I thought I read somewhere that they are interchangeable, but could not find it anywhere here on a search. I need a set of rear exits for my 64 Dart which has an 89 360 in it, and have a chance to pick up some free 318 rear exits..

Thanks for any knowledge, I appreciate it!

Years ago, I bought a 77 Ramcharger (360 engine)with a very noticable exhaust leak. To make a long story short, the leak turned out to be coming from the bottom side of the exhaust manifolds. The manifolds were from a 318 and did not cover the bottom side of the 360's larger exhaust ports. I bought a set of 360 manifolds from a local junk yard. Once installed, no more leak. Moral of the story, other than the bolt pattern, not all small block exhaust manifolds are the same.
