Re: Damage To 430 Cylinder Wall What to DO?!
As long as there are no scratches up and down the inside of the cylinder it should be OK, in my opinion. I have seen a lot worse used with no problems. Only the tip of the piston skirt is protruding, and only at the bottom of the stroke when there are almost no side thrusts exerted on the piston. When the piston is at the bottom of the stroke there is no compression or combustion pressure, and the connecting rod is parallel with the cylinder , the only thrust would be from bearing /lubricant drag in the direction of rotation. Just make sure there are no sharp edges at the piston side of the block. Also if you want to use used pistons, you need to check for proper clearance for each piston, and cylinder taper. The other thing I would do is carefully take the oil pump apart and see why it seized. Of the two engines I have seen with twisted drives ,one had a piece of hard sludge between the gears the other had a coolant leak and formed a sort of varnish that stuck the pump. Not That you would use that pump but you want to make sure you have corrected the original problem. Of course measure your crank also and all the other standard overhaul procedures.

The mock up looks good to me. If your pistons are original. Could you please take some better photos of the pistons at different angles clear enough so that they may be added to the Piston / Chamber thread.
