340 oil level?

I have a 72 340, just changed oil after break in. stock pan, stock motor. I put 5 quarts in and it shows way over full. Could the dipstick be the wrong dipstick? I purchased the block with pan and no internals. It showed over full with the break in oil, but not as much as this. I would assume the 340 takes 5 quarts as do most v8 engines.

Any ideas wanted.
Thanks!!
