KRC Performance has the components for a Custom Return-Style Fuel System,
these provide the ability to Custom tune the Fuel Pressure and Volume of
fuel to the Engines Requirements......
A stock or near stock Magnum V6 or V8 can make due with whatever system it
was built with....
Supercharged,Turbo, or Stroker Magnums can use the ability to custom tune
the Fuel delivery needs
to meet the engines Power output levels for a precise Fuel Metering and
Volume ....

One nice thing is that with the older systems, you got a fuel filter
instead of just depending on the internal sock. Another is that with the
external regulator, you could tweak the fuel pressure if needed, and a
third is that they were nice for running a dry nitrous system since the
fuel regulator could be bypassed to provide additional fuel by the nitrous
system.
But overall, for normal use, I don't think there is really a
huge advantage one way or the other. The returnless system has the
advantage of half the lines to rust out, less parts to break, etc.
Probably the easiest thing to do would be to replace it with the same
system you've got, unless the price difference is so huge that it
makes economic sense to go in a different direction. Then again,
since you plan to go to a 408 in the future, it might be worthwhile
to get the ability to easily tweak your fuel pressure. (I'm not
certain how the fuel pressure is adjusted with the returnless
system, but I'm guessing there is a regulator of some type built
into the pump itself, and the "fuel return" line never actually
leaves the tank.)

: for now?
I think it would probably build up too much pressure in the fuel
rail. If you did go with a return style pump, I'm guessing you
would also need to install a fuel pressure regulator (even if you
just put the regulator right there by the pump, under the bed).
