Determining required injector size

So my 350 is in my car but I'm relatively confident that I need larger injectors but I'm unsure on how to determine what size to get. I have the lt4 hot cam with 1.6 rockers, stealth ram, bbk 52mm throttle body, and engine quest 190 vortec heads. I was thinking that 30# injectors would be sufficient. I'm currently running 21#s.

Re: Determining required injector size

Minimum I would go would be 24#. I think 30# is right on the money.
