    TBI spacers and adapters

    There are also a couple differant TBI units. one with 2 holes seperated and one that has center open.

    Divided.


    Open


    I beleive the open ones came on Camaro and Caprice. With that in mind and proven results of CFM Tech spacer that has a split opening for divided TBI

    We used the divided TBI and made the adapter open while also machining the intake for straight shot passages when we made the TBI adapter at the machine shop for my sons 345 IH motor.
