This one has never been machined before. I hope they don't have to do anything but a .030 bore. Hopefully the deck won't need machined. I would rather keep away from the 10.5:1. Anything above 9.8 I fear will be an issue.
I can guarantee that your deck needs to be machined. It's a small block Mopar. It is not square to the crank from the factory. Every one I have every seen needed to have the block square decked. The T/A block that I built was off less than all of the others, but still needed to be square decked.
