Doing my homework on my Hilborn efi conversion. I know stock 5.0 mustangs use 19lb injectors. What's the rule of thumb on going up in injector size? My combo will be comp cam w/290 duration approx 560 lift (gross) (hydraulic). Headers, heavily ported 351W heads (flow about 315 intake, 290 exhaust), about 10.5 compression, 5 speed tranny, 411 gears. As always, thanks for the help!
