View Full Version : 5m or 6m intake manifold?
09-21-2011, 06:06 AM
Im working on my 6m swap for my '84. With a bit of research on the forums, I got the 5m out no problem. I seem to recall reading somewhere that I should use the throttle body from the 5m but what about the intake manifold? I live in Florida so emmisions are not an issue and I'd like to delete the egr anyways. Any advice is appreciated.

You could go with either plenum. If you use the 6M plenum, you only need to block off the EGR port at the back of the head. Whereas if you use the 5M plenum, you need an additional block off plate on that port location as well.
There's no performance advantage to using the 6M plenum over the 5M plenum.
