torque converter question

[bls33]

You could have the 258 flywheel rebalanced to match the 360. I believe you can get a brand new flexplate from places like Auto Zone. I know www.oldcarparts.com has them for about $100 new.

would i have to get the flexplate balanced?

AMC V-8s are externally balanced so weight is added or removed from the harmonic balancer and flexplate or flywheel, the I-6 is internally balanced so the flexplate is neutral balanced. To use the I-6 flywheel you would need it balanced.

If you buy a new one made for a 360, it's usually balanced "close enough" for a daily driver. I'd have it checked for performance use (high RPM).
