Also, do you think the BB TBI will be necessary? I have a SB TBI that I have rebushed, done the “ultimate” mods to and refreshed with AC Delco rebuild kit. I have a set of standard 350 injectors as well as a set of cop car injectors that were flowed by Witchhunter some years ago. I was hoping to sell the BB TBI if I don’t need it to recover some costs.
