Hello I’m new here and I’m new in the restoration cause im only 19 and still in school studying restoration, any way I just bought a 1960 bonneville for 4,500  it has a 1964 engine 2 bbr and auto transmission and runns well  id like to sawp out to an original tri power engine from 1960 if i couldbefore .  I want a posi for it and a tri power intake with the carbs. I was wondering they make reproductions or ones that are close cause i dont think its a tri power car at least its not now and what exhaust headers I could put on a 389 and what years are non compatible thanks
