this is pretty generic of a question, if you are currently running stockers, then 42s would probably work...

Given you are going dual pumps and you are also looking at 750hp I'm going to say you probably need at least an 80lb injector. I'm running 93 octane and planning on about 750whp on 60lb injectors. Thats nearing it's limit for my setup and running e85 will require more fuel. What is the rest of your setup?

For peace of mind give lonnies performance a call. Tell him what you are doing and he will have recommendations for you. My gut tells me he is going to say 80's, but he knows fueling way more than I ever will.

If your shooting for 750rwhp I would look at some 95lb high impedance. Thats what I just ordered for my setup, but im not running E85, Im on pump.. I was just wanting room to grow later on.
