I'm thinking of a 4.2 conversion using Brian Crower stroker kit and boring the cylinders in my 2012 3.8 track A/T. Are the stock injectors enough or do I need bigger injectors. If I just have the have a three angle valve job (port polish) do I need bigger injectors? I just want my Genny to breath better to accommodate my SRI Injen and Jun BL GT dual headers.
