I'm new to this part of the forum so I'm not sure where this post would go, mods please move this post if need be.

I have an set of Cosworth WRC Zetec piston and I was told the compression is 8.5.1 is this true?

Will these piston fit into an WRC CGI block?

If so then where can I find the WRC Zetec rods and crank shaft from????
If not then I need to sell these
