Scat crank thrust bearing killed again

That was my next question... How did it fit the hub? And last, assuming you have not dialed the transmission case because most don't - but it might be a good idea if the block was align honed.
"...the flex plate gets its name because it will flex forward and backward as the engine rpm increases. this is due to fluid pressure inside the converter as well. as any front to back movement of the snout by flexing the torque converter is able to float in the crank hub..." bottoming of converter is also addressed...
