I have one that I KNOW is going to be fine when it's rebuilt.
I have 1 other core that I had sent to me that needs inspected and another loose one on 1 of the 2 engines I acquired last night.
Hopefully the last 2 are rebuildale, as I need one for my own project, yet.
I'd hate to say a price unless I know it's tight and worth what I quote.
Mark.
