Something else to consider in the "versus" chart.
Since you aren't turning your own wrench, there's a very good chance that you'll definitely be spending more money than time on this car.
The question I always pose to people is this: Since you aren't turning your own wrench, and given the amount of money you
expect to spend *chuckles*, could you just buy a nice '63 driver with that money and be done with it? You could sell this existing car as a very respectable rebuilder for someone that has the time, knowledge, and money, and then put the money from the sale towards a ready-to-go driver.
It can be frustrating to see all your money going to a shop and having the car spend most of it's time there as well. Depending on how much time you are expecting to spend, it still could be another few years before you are able to spend an entire day driving it and not thinking about the next part to be fixed/updated.
However much money you expect to spend, multiply that by 1.5 as your actual realistic number. 10K becomes 15K, 30 becomes 45...
And on to a different topic... always focus on the safety features of the car first: Brakes & steering/suspension.
