Hi,

I'm looking for some high compression pistons for my 686 engine. What are the best pistons to buy nowadays?
Who has a coated Namura or Ross piston? What's the differance between those 2 and JE or Wiseco? Can you notice a differance?
Can anybody tell me how much the Wiseco, Ross or Namura weights?
Somebody has to know or does nobody balance his raptor crank when they fit a carrillo and large piston?

 

Craycraft....Craycraft is like, the best for the 660.
