Hello all,
Does anyone know what the difference is between wide deck and narrow deck engines, and which would be more desirable to power the 7? thank's for any help

Hey Ron, Im not an engine genious or anything. However, a search on the web seems to indicate that one of the large differences between a narrow and wide deck engines would be the size of the flanges that are used to bolt the cylinders onto the case. Apparently sometimes the narrow deck engines also used a plate to help bolt the cylinders on. There is some more information here. If I find more Ill let you know.

thank's for the help spike, it is greatly appreciated. I just ordered a RV-7 qb kit, and can't wait to get started. This will be my second flying project, my first build was a challenger II amphib. This project is much different, and I dont know much about the Lycoming, so having a resource like this is going to make life much easier.
