Just wanted to know what your takes on the different efi kits that are offered out there. Trying to plan out my build for this winter. Gonna be a 454(maybe bored a little bigger), Whipple, all new internals, hyd. roller cam, aluminum heads. Nothing to crazy, just looking for 600-700HP. Dont want to spend a bagillion dollars either. Have a 7.4MPI now so dont know what mods ill need to make if any to the tank, lines, pump, etc. Im new to building an efi motor. Will a tbi setup work or do i have to go with multi port? What are the good and most importantly best priced brands? Thanks.
