I would like to know what flexplate/flywheel do I need to have? I have a 73 olds 350 eng. and i need to buy a new Flywheel and I will be running a 2004r behind it. So do I need a 350 flywheel or a 307 flywheel or are they the same?

fyi Im getting the eng blanced and my machinist needs a flywheel and harmonic blancer to do it. I have the org Blancer but the flywheel was cracked!

Thanks your help, Kris

 

I think all Oldsmobile the flywheels are the same.

Thanks, I went ahead and order both there was a 4 dollor price diffrents...But my brother is my parts man and he was unable to tell by the cumputer pic.

 

Diesels are different, but I'm just being pedantic.

Apparently the FWD 307 motors also use a different (slightly smaller) flexplate. This was a surprise to me, too.

Just use the original flexplate for your 350.
