I have a piston and cylinder for a King Cat or 1M 900 big bore. The piston is a Wiseco, Has the numbers 1356A and 9612 on it, and the diameter is 90.85 to fit a 91 MM bore. I found a used piston on my shelf that says 1010 and is 91.87MM, so I think this cylinder and piston must be a 990. Not sure whose kit it is, but the sled came from Woody's in Caldwell, Idaho. The piston only has about two miles on it, the cylinder is in great shape. The previous owner had the kit installed and only made it that far and lost a rod. The other cylinder got trashed and was thrown away. I'm thinking around $250 for the cylinder and piston. I have the heads too, but they are dinged up a. I also have an extra set of power valves ground for the 1010. Also the used 1010 piston could probably be polished up a bit and used, make me an offer. Send a PM or call at 208 652 3416 or 390 2561.
