We've had a few guys measure what seemed to be excessive (beyond OEM spec) crankshaft thrust. Then again it may have been their method of measurement as I'm not certain they had access to proper measuring tools or methods. Be that as it may, the thing to remember is that the torque convertor also has the ability to float back and forth, mimicking the crankshaft. So.... before jumping on that bandwagon I'd make certain of the existence of the alignment dowels between the engine and transmission. They accurately locate and match the two together - the bolts alone WILL NOT do that properly (at least not without an extraordinary amount of luck.) This causes the flywheel (flexplate) and the convertor to rotate in two different planes and cracking will inevitably occur.
