@TJ: That is good advice. I will take note of the recommendations. Thank you for that. As for the 250 block, I was trying to keep the original because the car is numbers matching. Everything is original and rebuilding the 230 was appealing. This is not going to be a drag car or auto-x, more of a weekend cruiser.
I do want enough power to pass someone if I need to up on the mountain roads.
