1980 intake manifold 1985 exhaust manifold???

Is it at all possible to use the 1980 intake manifold with the 1985 exhaust manifold?

I see a problem with the EGR interconnect & the fact that the 80 should bolt together Intake & Exhaust.  Why would you want to?

Are you close to Seattle? I have an '83 J10 intake/exhaust and BBD carb (all functioning) for $30

I am not using the EGR interconnect I am in New York its a ways away from Seattle LOL but thanks anyway

You may have to grind down the riser mounting on the bottom of the intake a bit. The later exhaust sticks out a bit further than the 80, but I don't believe it affects the intake so much as the power steering pump bracket.

So the 85 power steering pump bracket is not going to bolt up to the 80 intake??

It should be fine on the intake, the mountings there didn't move; an 80 bracket won't fit over an 85 exhaust without cutting. Sorry, not sure what mix of parts you're using for everything

The '80 intake is conjoined to the exhaust manifold. Later intake flows better.

Your kidding....I would think it was the opposite way.

The aluminum intake and exhaust combo was actually redesigned by AMC to be better flowing, not just lighter. There is a wider radius turn down on the exhaust manifold for less back pressure and the aluminum intake flows quite well, even with the heater sticking up below the carb. I recall even seeing flow bench numbers on that at one time, but I can't remember where.
