fuel injection

Haven't bought it yet, but I am personally planning on going with the atomic EFI made by MSD. On my 440 build. It's a self learning system. It will also interact with their ignition and allow you to set idle timing and max timing. The big things with it from my research is the standard fuel pump will only support up to 525 hp IIRC. Most of the system is plug and play. They also have an upgraded fuel pump that will support up to 625 hp. The draw back is that is the most it will support. If I remember right the max hp is 625 and there are some limitations on cams as far as durations and lobe center lines. I am going to run a Lunatti solid roller 60331 cam and everything I've researched says the system will work for it. Do a search on this site. Been a couple posts and for sure at least one member that has actually used the MSD.
