    Any one know if you can interchange any of the TBI parts between a small block and a big block? Might the injectors themselves interchange or might the entire throttle body? I am trying to find ways to get more CFM for my truck.
    Thanks for any advice,

    The 454 TBI will plug into everything on your 350 wireing harness except the IAC valve. But you can get an adapter for that from turbocity.com. You may need to get a new chip burned. I think turbocity can help you there also.
