Ouch! I'd say it got really fat, lifted the rings then started eating itself over several outings.
What coating are you using on the bearings? My last 3 motors have all failed from rod bearings. Last one got about 20 passes before it siezed a rod bearing with a 300 shot. Took out 3 rods, 2 pistons, crank, block and a couple valves @ 140+ mph.
I did manage to save your old cam though
