Default 5.7 2 barrel carb to 4 barrel

I have a 1996 Mercruiser 5.7 in with a 2 barrel, What manifold and 4 barrel switch out would you recommend? Will I gain anything? Thanks

Might get better response in the Tech section. Find the same carb that the 350 4 barrel uses and jet it the same to Merc specs and you should be fine.

RPM Air gap and Holley 600cfm would be my choice.
