I ran 74/82 in my 850 on my 408. Our combos are different, so we take that into account. Dom told me when your jetting is close at wide open throttle you don’t have to get you hands wet doing jet changes. Just change HS bleeds and your golden. I tried this last time at track and it works. Wide band was reading 12.7 thru traps using 28HS bleeds in a Dominator. I switched to 32’s and then seen 13.3 on wide band . Car went quicker and faster mph. It works.
