Hey does anyone know if a 1977 Plymouth slant six manifold would fit a 1982 dodge d150 slant six?

Yes, it will. It is very much worth your while to get the good gaskets for the manifolds-to-head and intake-to-exhaust junctions.

Okay thanks a lot, mine has a leak and I’m looking to change it with any parts, an I forgot to mention that it was an intake manifold, still the same right?

Yes they are the same. Your's is aluminum?

I’m not even sure if it’s aluminum, how do I tell just by looking at it?

Aluminum is a silverish color underneath the paint. Cast iron likely has a rust sheen, but it is black-grey if you sand or clean it.

Cast iron intakes rarely fail outright. Why are you believing that the intake has a vacuum leak. What leads you to believe the intake has failed? I am not questioning your belief outright, but trying to make sure that it is not something else that is a comparatively easier fix...

It would seem to me that the vacuum leak is in the gaskets, or somewhere else, and not the cast iron intake itself.

Is a magnet attracted to it?

Intake manifolds don't need replacement for leaks very often. Sure it isn't just the gaskets?

The Remeflex gaskets that SlantSixDan suggested work great and that may solve your vacuum leak issue.
