Default how much injector will i need?

I'm having a 370" ironblock setup with 11* et heads, big solid roller, setup with a single plane victor jr. manifold with an elbow, nitrsous express plate kit etc. for the fuel system i have a sumped tank, weldon pump/filters, nasty performance rails, -10 feeds, -8 return, just curious what you guys think about injector size for the motor.

I think you would be okay with a set of 42 or 60s.

It is important to know the projected power level to help choose the right flowrate . Just trying to make sure you get the right ones so you don't do it twice .

Eric at HKE says roughly 600 on motor, then a plate shot of 200 and possibly 300. the nitrous hit will have a stand alone fuel system so that shouldn't really come into play.
