Aftermarket Components for the 383E install

From everything I have read on this engine, the new 383 uses all of the external components (including the ECM) from the original 5.7 (350).  My question is this...  Will aftermarket performance products that are designed for the 5.7 also work with the 383?  Items such as intake manifolds, throttle bodies, and (the BIG one here) a supercharger??  This engine has a mild 9.1:1 compression ratio, so I don't see where this would be a problem.  But with all the gadgetry left over from the mild-mannered 350, I would like to know how well this engine would take the extra oxygen.  Any help on this issue would be great.

I think most components designed for the 350 should work with the 383. Only difference is a slightly longer stroke on the 383. I might go for higher-flowing heads, a slightly more aggressive cam, and other components, to facilitate the greater airflow for the bigger engine. Of course, if you're just looking for gobs of torque, you could probably get away with a more conservative cam, since it will have a lot of low-end by virtue of its long stroke.

almost anything for the 350 will work on the 383
same block, just different crank and rods, etc.
