Hi to all. I'm Paulo from Argentina. I have a 400 with TMeyer pistons. I'm now running a Barry Grant Road Series 625 CFM, MSD 8477 distributor and 6AL multi-spark box, but I'm planing to get a bolt on EFI system. My carb has a nice throttle response but I think this EFI system could be better. Also, EFI has another advantages. I couldn't contact anyone to use a Terminator EFI on a rig like mine. The first thing I see is that this system is 900 CFM, and I do not know how to calculate the necessary EFI system CFM, like you do for a carburetor. I was watching Danny Cabral's Bronco and I think he could answer many of my questions. Thanks, Gracias
