    I've been looking for a flywheel for my 6.2. On summit they have a few listed and they are the same ones listed for the 350 of the same era (83'). Are they the same? If they are it might be alot easier to find one.

    6.2 diesel flywheels

    The Summint listing is incorrect. The 6.2 manual uses two different manual flywheels. If automatic, it uses two different flexplates - one for the TH400 and the other for the 700R4. With any of them, the tooth count is 139 which is not used on any of the gas engines. Most Chevy gasers use 168 teeth. 6.2 uses a 12" clutch.

    Most common manual-trans. flywheel is: DIESEL CASTING # 14050525 weighs 45 lbs. GM part # is 14077160.

    LUK 6.2 manual flywheel is a LFW-201 and fits all 6.2s 1982 - 1993.


    Perfection Clutch sells the manual flywheels new - i.e. no core-charge or trade-in needed. I think Autozone has them. Their part # is 50-2710.

    TH400 automatic flexplate is GM # 14077157

    700R4 automatic flexplate is GM # 14077158
