Ive got a 408SBF with a Carb shop 850,AFR205s,super vic,and a 540 lift roller cam.Im running a NX genini plate setup and wanted to know what you guys suggest on fuel pressure?Im at 8psi on carb and 10psi on Nitrous fuel side.Book says its a 175 shot.Thanks guys.
I was running a blower with this same setup.

on our 408 we run 71/4lbs fuel pressure for carb and nx says 10lbs is very safe for the nitrous,but we run between 8.5 and 9 lbs is still safe. call them at nx they will tell you the fuel chart.

i always ran 7lbs for the motor and between 5.5-6 lbs for the nitrous
