    Hi,
    I've been looking for a th400 for my 350 Buick. I know there's differences between the bell housing bolt patterns on a 300 to 455 series engine to a nailhead. What about a th400 that's out of a Chev,Chev truck, Pontiac, Olds, Caddilac. Will any of these bolt up to the Buick 350 :Do No:
    Thanks Bruce

    GStage1 Always looking for parts!

    BOP use the same pattern. Chev is different
    Nailhead is different. You can get a shortshaft TH400 from all 73-77 Pontiac Grand Prix models and some 77-80 full size models.
