Spotted this wicked hot rod at the Back to the 50s Car show at the Minnesota State Fair grounds which was celebrating it's literal 50th anniversary!

I snapped this photo just before the owner who happened to be standing behind the motor started it up and believe this sucker was extremely loud, I unfortunately was standing very close to when it started right up and made my ears ring for 2-3 minutes!

The engine's sound reminded me a lot like a modern monster truck if not louder.
