my 340..3 cars, 34 years, 1 family. where to go from here

I agree with the memory sometimes being better, but none the less, a light car like a 66 barracuda with 3.55 gears should have no issue breaking the tires loose, and that wasnt the case after the rebuild. I believe my father said the machine shop had to sleeve some cylinders... .60 over is about the limit for a 340 right? Can they resleeve the damaged cylinder? This motor has too much family history to give up on.
