I am prob. going to be told to search this issue but I have been and haven't found much or just suck at searching...

I am looking to purchace a block that has been bored out to 91mm from a guy that cannot finish his project. I am not looking to boost the crap out of this motor just replace mine due to factory piston failure. It is an golden eagle block. What I was wondering is I am hearing such things as offset bore and this and that.

What I want to know is this true? Does a custom made crank needed for this application. If not than what if anything needs to be done to the factory crank? Or do the rods need shaved?

LAst off where can I find pistons for this application and are they a custom make?

Shed you knowledge upon me it would be greatly appreciated!!
