I'm going with a 230+ duration cam on a 110 or 112 LSA with satge 2.5 5.3L or LS6 heads. Should be around 450+ HP to the rear wheels. I am planning on running 42 lb/hr. injectors and having them tuned down so if I upgrade any further I won't have to buy new injectors. Not sure on how aggressive your cam/heads and how much power you're making though. That would help gauge what injectors you need.
P.S. I believe if you get the car tuned they can check what % duty the injectors are running at. I don't believe they should be over 85-90% duty.

yes you can check the duty cycle with a scanner...at least i believe so. if you are expecting 450HP N/A 36#ers will do you fine **IF they are rated at like 30psi; such as the SVO green tops i believe ; but you might as well go ahead and get 42#ers, get you some disc injectors instead of those pintle ones. I'm running 42#ers
