Blocks right here!! Iliinois
I have a 109 block that I was going to rebuild but I went a different route. I know it is standard but it does have a good ridge on the cylinders, but 20 should clean it up nice. It was pulled 2 months ago and reason was I spun a few bearings. I also have a real clean and standard bor but will clean up with a hone job hot air 040 block. Let me know. I am in Illinois about an 1 from the Iowa border.
