i tried q16 against c12 in my 13.1 small block stroker it was worth a tenth but you might have to get into changing the air bleeds i couldnt put enough jet in my QF 1050dom.i believe it has 10%oxygen the 113 is 6%or8% so might be better suited in your application.i wanted to try the 113 but was hard to get ahold of around here.
