I have been down the MPI road as well. Will always be your limiting factor no matter what you do to it. If you are handy with a die grinder you can get some good gains, but not as much as going to a single plane intake and 4bbl throttle body. The MEFI computer and setup can run on any intake once tuned. Pretty basic efi system.

I didnt invent the runner mod, its been a common thing done time and time again, do the mod, bore your throttle body at same time, put a little cam in and head work and you will make 500+ reliable hp, shortening the runners gives up a little tq and gains hp, going to a open plenum gives up even more tq but will give you impressive hp gains for less money, fwiw, smitty
