All this information helps a lot. It looks like I may have found a better car to begin with. Not better as in faster, but better as in condition and that will fit the goals of the learning experience. More room to work due to size, and the car is in better shape, I have a few 8.75 3rd members on hand etc. so things will likely go a bit smoother and faster compared to narrowing an 8.8 etc.

It is a 60's B body. My guess is I am going to gain a solid 500 LBS. so that may make my 12 second goal more elusive.

But I think it is still doable. I have a modern GTO and I would like to be faster than that which I know I can be. It is a hoot to drive, but it is shaped like an egg.....
