Thank you for all the response guys :cheers:
The engine lost more power for every run, from 12.2 to 12.8.( about 0.1 sec /run). That the reason why I tore it down.
No noise and It never took any water.
The dents line up with the groove in the piston at bdc.
This engine has been raced for over 8 years and tore down every year at the end of the season and the bores have always looked good.
This is soooo strange but I will mesure the cylinder walls and pistons today and get back to you
thanks again!
