During organizing matrixes and forms I've found one undisturbed matrix of crankcase. I thought that each of matrixes has been damaged! I've just prepared a form for a 5 pieces. I'm going to release 20 pieces of a good quality UI (I have only 20 pieces of valve rocker sets - matrix is definitely destroyed...).
If You are interested in this engine, let me know via mail - first casts will be the best quality.
You can also order in my www, the engine will be available in this week.
The price will be normal - 37.5$. In another thread I'll try to clarify my pricing policy (why my engines are so expensive)
All the best, Lukasz
