First off, egr/non-egr manifold doesn't really make a difference in
performance...just the non-egr one is cheaper if you can find one. :)
As for a 408 manifold....conventional wisdom is the larger the cubic inches,
the larger plenum volume you should have. In other words, the 4bbl
manifold would probably be better. By how much? Who knows. If it were
me, I'd go with a 4bbl manifold and a 4bbl TB. Unfortunately, I don't
think new M1 4-bbl (FI) intakes are still available.
Alternatives I know of are....Edelbrock magnum Air-gap for a carb can be
modified for fuel rails. Hughes Engines does this....and they're real damn
proud of them too! LOL Another alternative is the Edelbrock LA FI
intake. It's a single plane, 4-bbl intake. To use that you would need to
have your heads drilled/tapped for the LA bolt pattern. (Hughes does that
too.)
