1. It's the original just rebuilt. 1969
2. I'm not sure I told him a 340 was going into it and ask him to beef it up if he could so I'll ask him again what he did to it next time I see him.

Ok. As long as it was done right and a decent shift kit such as a trans-go TF-2 was installed it'll be fine.
