  • multiport injection

    I have a Gm multiport setup from a small block motor, I would think i could drill out the bungs for the injectors to make it work, has this ever been done yet?, and do i then design a throttle plate for air intake. I would like to find out what size injectors you would need, i was thinking 454 motor, i have a 392/40 over=399 cubes.:confused:

    Sounds like a good project.
    What about just using the BBC TBI throttle body without the injectors for the throttle plate? Or just mount the MPI or TPI throttle plate straight to the top of the manifold then just run a cold air kit to the filter.
    The fuel rails would be the only tough part.

    I say do it.

      Well the manifold end has been done but I have never seen the system completed. Just looked for 1/2 hour and can't find the picture of the intake with the injectors installed.
      The throttle body end would be easy, just use the tb off the same GM donor.
