jahns pistons

FYI, there is a set of Jahns pistons and pins on eBay 12.1 .125 over for a 348. I didn't know it was possible to bore one out that far.

Wall Art! There's no way in heck that those things would get any closer than that to the inside of my engine!!!!:no
I have a set like that that are .125 over as well... also have the matching .125 over 011 block that they came with... and the block is an FH block as well... not sure what I’m gonna do with it other than keep tripping over it... LOL
