Scat crank thrust bearing killed again

good points all
check finish on crank and that thrust is parallel- I've seen them like files and warped- ground too fast
I drill through the thrust with a 1/16 then through the block into the main feed around .040 then put a cup around the thrust hole
I also use the bearing scraper and relieve the parting lines from the oil groove back
I've had trouble with stick shifts also
Anyone use Gil Younger s trick of cutting through the flexplate holes on the following side
Gil's theory was that the flex plates were too stiff
RIP friend
