Here is a chart showing the different piston sizes, stroke and cubic inches for the various production engines being used in Badger style Midget competition. I show this because it tells you why you can't just say "stock" for engine size. You can see that the max of 148.82 CID was chosen to make sure the Chevy guys got as much time out of their block as the other engines. It wouldn't be fair to make the Chevy guys buy a new block every season just because they had to run a hone through the cylinders. Also, with these engines it is a lot easier to sleeve one down than it is to make it bigger due to the bore spacing of the engines. Just trying to show more information and help people understand where and why the rules are as they are.
