Plug read, opinions needed

Rusty, this engine was run and tuned on the dyno during one full day. The engine is now on a pallet mocking me waiting for me to install it in the boat. I pulled the plugs after the last dyno run to get a read on them. Trust me there will be some testing done after it’s in the boat, but that is impossible now.

Well it looks good! I love the old Mark IV engines. They can make some big power.
