This is not a rare numbers matching car just simply a 340 'cuda with a 69 340 in it. As you can see dowel pin that's been drilled in the block and trans clearly isn't stock. The outline of the original dowel location can be seen just below it. I was tempted to put the original dowel in the trans, then lift up to seat it in the broken area and see if the hole that drilled for a new dowel would actually line up. Basically at this point I have the option of trying to limp along with the 340 or installing a 318 because I'm not in a position to spend 3 - 4k to get a 340 built.
