You need to replace the powdered metal rods Ford used in the n/a versions of the engine with a set of Manley's (or comparable) like they use in the Terminators and supercharged Coyotes.

p.s. Other stuff you will minimally need to do;

You also need to replace the n/a pistons and it has nothing to do with the c/r, although you ought to give special consideration to that also. A supercharged engine is hard on piston skirts and will collapse the skirts of an n/a piston very quickly. You need a very significant increase in skirt thickness if you want the piston skirts to survive in a supercharged engine.

While you are at it you should also upgrade the wrist pins to tool steel pins with a wall thickness in the neighborhood of 0.180" or thicker and get rid of the moly rings.

The first time you experience preignition / detonation you will knock the moly out of the OEM rings. The ring you need for the top land is a TotalSeal AP series (or equivalent) steel ring.
