    PM sent. Looking for 1227747 computer with the 28-pin conversion, and one of the chips tuned for a Buick 350, manual trans. I have VSS output, so would like highway lean cruise enabled. I also have knock sensor installed.

    TBI system runs both EFI and ignition through a converted HEI distributor (no vacuum advance, mechanical advance welded).

    Thanks!
    Thank you,
