273 Cylinder Bore .004 over spec

Real? You ever built one (on purpose) at .007 skirt clearance? I have. In fact I just did. I told my machinist to set the skirt clearance at .0075 because of the way the engine will be used. Turbocharged in a boat constantly loaded. He didn’t want to do it said the pistons came (Mahle before you ask) at .005 and that’s where we should run it. I said make it .0075. I’ll tell you this it ain’t no minivan where you turn the key and go jump on the freeway before things get up to temp. You have to warm it up, you have to get the oil hot before putting the coals to it, or you’ll be picking up pieces of piston off the ground. That’s real. No bullshit. His is too damn loose to throw back together and run it. The DLC coating is a good idea and will work. They can coat pretty damn thick and it’s abradable so it will wear in its own running clearance. But other than that, it needs to go to the machine shop.

Yes, we grew up poor. We would take a good, well taken care of engine and build a "throw together" engine, usually under .005 wear, clean up the block. Torque the mains to spec. Torque a honing plate with a used head gasket onto the block, and hone the cylinders till it would just start to "scratch? the wear at the top of the bore. Next file fit and stone the ring ends on a set of Speed Pro +.005 file to fit rings. New rod and main bearings, rod bolts, high pressure oil pump spring, windage tray, brass freeze plugs, cam, lifters, valve springs, double roller timing set, exhaust valves, gaskets and seals. Mill the heads, tighten up the exhaust guides and do a good valve job. As a matter of fact, that was the 383 engine in my 68 Formula S Barracuda. I did in the late 70's or early 80's. It came out of a 72 Newport along with the 727 transmission and 3.23 sure grip gear set from a Highway Patrol car. I'm just pulling it to put the original block back in this year. So what do you think is the problem? I can tell you it ran great, used very little oil and got good mpg for over 100,000 miles. How much money do you think I had in it?
