You should be fine with that setup, although alot of people upgrade to 42#s. You'll need to retune if you get bigger injectors. I have brand new Mototron 60# injectors for sale.

I would get some bigger ones if I were you. I was at 89% duty cycle with 5.3 heads and a 224 cam.

I would get 36 lbs injectors for that setup. If you add more power or nitrous, upgrade to 42's.

what brand do you all prefer and would it hurt to go a head and get 42# injectors? just incase i decide to put my nitrous back in?
