Question Flywheel Interchange
I'm installing a 67' 330 in place of a 69' 350.
Will there be any issue's on using the 350 flywheel.

Other than it won't bolt up, no...

Olds motors used a different crank flange bolt pattern for 67-earlier motors. You need one of those flywheels.

The counterbalance weight in 68-up flywheels is different from 64-7 also. That is why the bolt pattern was changed.

Actually, any 64-67 Olds flexplate will work.

Considering the posts in this thread are from 2007 and 2010, I hope they got their flywheels long ago...
