Well, made a few 12.6 passes early in the day. Car was running great on what little borrowed time I knew I was on. I had my 2-step launch control set too high so I backed it down to try and keep from spinning the MT's off the line. 3rd pass something let loose right at the big end...all smoke and some nasty noises. I coasted to a 13.00 and turned off the track. upon initial inspection no oil dripping or parts on the track. Cranked it and it started up hammering away..was able to drive it on a trailer. Thanls to David Neibert for the tow! Once home I had the engine out in a few hours to find....(sorry for the large pics.)

Number 8 connecting rod broke, smacked the piston into the valves and head 3 times, and punched a hole through the cylinderwall...but not the block. Piston exploded into nothing but the top and ringlands. trashed the crank, and chipped the #4 piston. Not worried about saving any of the old engine as the new engine was built and waiting....
