With all of this fine advice, I checked the taper on the cylinders. As Cliff noted, engines with little ridge on the cylinders are often lower mileage engines and make for good re-ring jobs. This engine had by far the smallest ridges on the cylinders of the Pontiac engines I've done. The taper came out very nice. Two of the cylinders had .0015 taper and all the rest were less than that, so the wear was very even. Still need to check the pistons and crank. I expect the crank to come out fine as the bearings have nice even wear that's not excessive and the crank looks great just eyeballing it. Not sure how the pistons will come out. Crossing my fingers.
