Was busy helping Aram Kazarian in the pits. He ended up blowing up his 900hp Joe Sherman SBC. I helped with the autopsy tear down today. Looks to me like a wrist pin keeper and spiral lock came out on #6, the wrist pin rocked and the piston came apart smacking the valves and taking out that cylinder ... Pieces of the piston and sleeve grenaded all over the motor... Sleeve may not fix it cause the rod took out some meat at the very bottom. Epoxy patch after the sleeve.... Maybe , the wrist pin is still in that rod as well. This happened at 8800 RPM. Pretty sure Sherman is fired! Lol
