machined, and by how much?
I went through this in detail when I built my 3.1 liter, using a spreadsheet program. The figure of concern is what I call the “installed piston height”. It is the maximum distance between the centerline of the crankshaft to the top of the piston with everything assembled. Or: installed piston height = [piston pin height + rod length + stroke/2] Piston pin height is the distance between the centerline of the piston pin to the top edge of the piston. Rod length is measured between the centers of the two circles formed by the big and small ends. The installed piston height along with the height of the block will determine the “deck height” which tells you how far the piston will be relative to the block at top dead center (TDC), or: Deck height = Installed piston height – block height This number can be positive or negative. A positive deck height is where the piston extends above the top of the block. Because of the thickness of the head gasket, this can occur without the piston making
