Rich did the EFI setup for my car. Has injectors both above and below. When I was originally going to do this he said if I was only going to do one of the other I think he said that it should be the ones above; but definitely recommended both. So I bit the bullet and bought a new intake, from Indy (not the Mod-man one) with the injector ports done with fuel rails. Motor was dynoed and put in the car but I have yet to drive it.
