    I am posting this for a friend who is restoring an old Jeep.
    He needs a manual transmission flywheel for a 225 Buick V6. I figured this was the best place to start.
    If anybody has one they are willing to part with/sell, please let me know.
    Thanks again for all your help.

    I got the flywheel your buddy needs and I would take $50 for it, but the ride is going to be expensive. I live in California so it is a long distance to his house. Let me know if you are interested and I wlll pull it out and see about boxing it up this weekend. If he wants I can probably get so pics of it Thursday evening.

    To make your search easier, a 300, 340 or 350 flywheel will fit.

    The only thing unique about the 225 flywheel is it weighs more, there's a extra ring around the outer rim to help it idle smoother. A lot of people didn't like the rough idle of the 225 that was caused by the uneven (odd) firing of the engine. Buick stopped offering the 225 in 68 and started using the Chevy straight six. In 75 or so, after the Arab oil embargo, they brought the V6 back as a 231 still odd fire. In 78 they off set the rod journals to make it even fire that fixed the idle problem. Then it became GMs second most manufactured engine (after the small block Chevy).

    Anyway, the 300/340/350 flywheel will also work but it's lighter and may not idle as smooth.

    Thanks for the info. I will keep this in mind if we need to go back to the drawing board. :TU:

    Are the flywheels for the 300, 340 and 350 all identical?

    I don't know for sure but I used the same flywheel on a 300, that it came from the factory on, and a 340 with no vibration. Then I put it on a 225 with no problem. The 340 and 350 use the same crank so I would assume it would be the same.

    The 300 and 340 have extra holes drilled into the perimeter, possibly for fine tuning the balance? ....or for dirt daubers to build in and mess the balance up for you.
    I have a 350 flywheel behind my 300, and it's fine. Picked up a 300 one later on, looks the same except for those extra holes.
    Have a V6 one here too. I'll have to take a closer look at it, but it is heavier.
