Cutting open a torque converter
Well either a Mopar TC or a Chev setup is supported more rigidly by the time it's "all bolted together" in the engine / trans. My concern is, that once you cut it apart, really, the only thing keeping things from flexing is the 4 bolts on the original flexplate. I do realize the TC has a centering pilot.
In the end, though, I tend to agree with you, but I'm not sure you "want" any 8K rpm with that thing.
