Hey z22se-fan.
The weather was too bad the last few days. I had a cold and did not want that they will get worse. But it will soon move on.
I read your post in the Dutch forum. The damage to the engine was not caused by the s / c conversion. The damage to the piston rings was present, but has been shown that after the conversion.
In addition, the engine power was significantly higher than expected, so the rods came about its limits. So anyway I had to use new rods. If I had opened the engine, I would have overhauled the entire engine and installed new pistons.
Now I have a better engine, completely overhauled, with better pistons and rods for little more money than the repair of the old engine. That was a deal i coudn´t refuse. This engine is now stable to 450HP so I still have some room for improvement.
Greetings Chris
