4.0 exhaust manifold on a 4.2
« on: August 11, 2010, 10:43:00 pm »
can anyone tell me if a 4.0 exhaust manifold will fit on a 4.2...the 4.0 one looks like it would flow a lot better than my 4.2 on my cj7

I dont think so because when i replaced my intake/exhaust gasket 4wd sent me one for a 4.2 not a 4.0. the 4.2 didnt seem to work on the 4.0.
