I would like a scientific explanation as to why the 1992-1995 version of the Magnum V8 intake manifold had a center divider cast in place that reached down within 1/2 inch of the bottom.
Was it there to block reversion pulses?
Was it there to more evenly distribute EGR?
A year after EGR was eliminated in 1996,
the 1997+ plus intake castings had the divider greatly reduced so that there was 4 inches of open area above the bottom.
In 1998 a new camshaft was introduced and peak HP at 4000 rpm went up by 15
I wish in 1998 that Chrysler had taken the science of V10 intake manifold and createda V8 version with 25 inch runners that would have peak torque as low as 1200 rpm resonate at both 1700 rpm and 3300 rpm. Magnesium and no troublesome plenum plate or gasket.

A Helmholtz resonator intake manifold was tuned to boost torque at 1700 and 3300 rpm. Long primary runners curved over the right cylinder bank to clear the hood. Resonance in the 25-inch primary runners enhanced low speed torque, with peak torque as low as 1200 rpm. Two plenum chambers supplied air to five runners each. Plenum chamber volume was tuned to resonate at 3300 rpm, broadening the torque curve. Passages across the longitudinal center of the manifold fed air from the throttle body to the plenum chambers.
