73 340 vs. 360 converter.

[Valkman]

I have 73 cast crank 340 in my car, and have 360 block I'm thinking of using to build a stroker. My question is does the 340 use the same torque converter, or are they balanced differently than the 360?

The 360 converter has more external weight to balance the assembly than the cast crank 340. But if you're building a stroker, or changing anything from OEM for that matter, you'll need to rebalance everything anyway.
