Are all 340 blocks the same?

I don't know the answer to your question, but don't listen to the 340 haters man, if you got the money to burn, let it burn! More cubes is more cubes.
You are just north of Mooresville correct? Did you go down to the Hotchkiss shop and get a chance to see Consulier's Dart Sport project when it was under construction?
Yes I'm one town north of Mooresville. I have not been to any of the shops, too busy getting established at this point. I have seen lots of drag racing though. Lots of 1/8 mile tracks close by so its not the long drive I had back in CT. I ran my Duster at Mooresville once when I first brought it down, drove it there, never even opened the hood and ran a best of 7.16@96 mph. Car is in storage now until we buy a house.
