Thanks! When you get into racing things like this happen from time to time! The short block I am going to build wont be giving me this type of trouble in the future! The Thrust bearing design on these engines make me scratch my head! So anyone out there with a stock bottom end LT1/LT4 that is pushing 900RWHP there is a fix for this... I sure wish I would have known!

It's a shame GM used such a shitty thrust bearing. The engine otherwise would be rock solid to over 1k whp. it's a gamble when you spin a belt driven supercharger hard...it pulls on the crank and causes the bearing to walk.

Agreed! The entire bottom end is bullet proof except for a $50 part!
