    Thought I would ask some of the experts. Following up on some research. Will a BOP 300 4-speed bell-housing and flywheel fit a Buick 340 engine? I would assume so but thought I would check. Thanks!

    Yes.... V6, 300, 340 bell will also fit the 350, 400,430, and 455!
    There are different pn's used thru the years. The later ones also fit engines with starter on left or right side.

    the 340's are a great engine. BUT you need to do your homework if you want more out them.
    alternative is the 350. everything bolts up. exhaust needed.
