[QUOTE="Catmonkey, post: 16115412, member: 124025"] You are correct, I posted that before my first cup of coffee. It would be like 54 hp, which I've edited. 3.7" is the largest piston diameter I see anyone offer for a Ford modular, as well as the largest head gasket diameter available. 3.68" is the stock 5.8 bore diameter. 3.7" appears to be the max anyone builds parts to accommodate. Piston clearance is only in the range of .0025"-.004" depending on piston and application. At some point, it's your only option, or throw the block away. If the cylinder is out of round or the plasma surface is too thin, sleeving would be the only way to salvage the block, but it also affords you the ability to go oversized on the next rebuild with just a bore job. With low miles, just a hone may be all you need to install new rings. I would let my machinist tell me what he feels is the safest route to go on hone versus sleeves on a used block. And then I would find someone to sleeve it that has done a number of these. [/QUOTE]
