Engine Weights

[dumbbelldaddy]

I don’t have an engine yet for my Pitts S1D but I’m always keeping an eye out for a 320. Stumbled upon this post on one of the cub forums. Don’t know how accurate/legit it is but I figure those that are really concerned about weight savings might find it interesting.
