367 vs 410 Engines Masters

If you watch the show it will give you the cost of the crankshaft. As far as the internal balance I think the reason they gave was ability to swap flywheel or converters with internal balance. No mention of a performance gain that I recall. It's an older video but worth a watch

Right. I believe what you are saying.

My point is in general terms.
This test illustrates how the strokers behave, and building a stroker is an extra investment in the shortblock that could be put elsewhere in the build if it works with the rest of the cars combination.
This test is useful for someone trying to decide how to allocate their funds for a build.
