ap72 and starnest,
I appreciate the feedback I have received from both of you. While it is somewhat competive between the two viewpoints, it allows me to ponder just where I want to go between the two. I have often questioned what I would do, if I find the 327 block needs both a bore and the crank ground, as well as the heads rebuilt. I realize I could go out and purchase a good running 350, bolt on my intake, exhaust, and a new cam and have a more efficient and powerful engine for less money. As for the sentimental reasons, part of my perspective, is I'm building a car very similar to a 67 I had 32 years ago. I'm now 55 years old, and part of my "mid life crisis" is to recapture some of the good old days I had when I was younger. You are right, it is not completely rational or financial, but to balance it all out, it would also be good if it was. With a set of headers, my design should put out about 300hp and 400ftlbs, and I'm still hoping for gas mileage in the mid teens.
Here's a photo of the current car I am building:
