What will you need to bolt this combo together? Tranny guy says you need a Buick 350 tranny to bolt to a 340, Is this true? Thanks for any info,Bob
Buick-Oldsmobile-Pontiac (BOP) share the same bell housing bolt pattern. Chevrolet has a different bolt pattern. As long as the THM350 was behind a Buick, Olds, or Pontiac, it will bolt up.
