400 stroker cranks

This is what I have been looking for. I know the 4.15 in a lot of kits has a very short cd and the rod pin almost/ does intersect the oil ring. I just wanted to know if it has been done.
My block is at the machine shop now. I will find out if I have a good downer Monday and my BCR aluminum caps and girdle will be here this coming week.
I want to build something different than the rest but don't want to loose my *** doing it or find out in need 1k of custom pistons after I buy the crank and rods. I just wasn't sure if the lower cylinder walls of the block would make issue with rod swing or other issues.
