Jet size can vary with application but if you are running a 750 on a small (351 or less) V8, you are over carbed and you will have trouble with getting good responce for it and good WOT performance below 3000 RPM or so too. Better is raely better with a carb because you need to maintain airflow velocity rates in the throttle bores in a certain range for best performance
