Joe - thanks for the feedback and the boring procedure. 
I would prefer to just take it far enough to clean up the "scoring" which I hope is 97.5 or 98mm.
Concerning piston's - I can imagine factory oversize could be incredibly expensive. What's a good source for a oversize 4.7 Euro?
Much appreciated,

I had all 8 bores taken to 97.5mm from 97mm there are still oversized pistons available at 97.5mm and 98mm for the 4.7's and also 100.5 and 101mm for the S4's and above.
the boring procedure is at http://joe928.joe_icecool.fastmail.fm/alu_en.pdf it's about 1.3 mb.

why dont you just buy our brand new 4.7 euro block? (almost brand new)
perfect cylinders, new rings, bearings and seals. a drop in for near $1000. its going to cost way more than that to do the clean up, bore it and then buy the oversized pistons. (or piston)
Its a euro M28-11 short block

Hi Mark,
My interest at this point is information and knowledge. In a recent parts deal (for parts other than a motor) - I ended up with an M28/11 mini-short block(no pistons) with a "scored" cylinder.
Thanks for the offer for the engine; however, right now I am just trying to understand if the damage (scored cylinder) can be corrected. If the damage could be corrected then this might become a long term engine project. If the damage could not be corrected, I will likely keep the block for one of the exotic coffee tables I see in the forum
Thanks again,
