Pretty tuff to remove the heads and retain the cylinders on a Lycoming.I thought a long block means it has heads where as a short block is just the block. It is fully dressed with accessories bolted on.
That is car and truck talk.
No idea. Can't say I've ever heard that terminology used before. Why not email Lycoming tech support?but I'm puzzling over the "long block" terminology used for the O-320 E2D. Any idea?
