My 318....Is no more..... :(

There made by united machine company for keith black.
They are silvolite pistons.1266
I talked directly to one of the top dudes at the company and he gave me a bunch of info on all the pistons they make.
This is the company that makes all the keith blacks pistons.
They are way better then the stock pistons of yesterday.
He said it was the material they use now that made them so strong, but most importantly, it was how they cooled the piston and how strong this change made them.
They are always testing new materials and trying to make a better piston.
