I hope I am doing something wrong as the pistons are anywhere from .021 to .038 in the hole but they are close on both sides of the motor. One side all 4 cyls are .036 to .038 and on the other side they are .021 to .026. The way I'm measuring is with each piston almost at TDC with the dial indicator touching the piston, roll the motor over until the dial indicator stops sweeping and then check with a straight edge and feeler gauge. Not sure if this is an accurate way to do this or not?? Could I be out .017 cyl to cyl measuring like this??
GM deck heights are all over the map as I am not surprised with your findings.
