I need to replace the block in my 841 gasser as it has broken engine cradle mounting ears. Casting is 310609. Fella on ebay has a block has one with the same casting number, but the liner bore and piston both measure around 3.997". I thought the bore is supposed to be 3.90". Seems a little on the large side. I plan on replacing liners and pistons - does anyone see a problem with me getting this block as a replacement? I'm potentially worried about the block being bored and larger liners being installed....or I'm completely wrong in my thoughts. Wouldn't be the first time...
