That is what I was thinking...
To look at the cylinder bore on a DLE, it is amazing the engines run as good as they do for the bore is not very accurate compared with some of the others.

I looked at my TF staggerwing, and although the specs say it has more wing sq's....I compared one of the wings, and this Waco has more that the staggerwing....

I am currently trying to figure out how I am going to place my saito 5cy in the cowl....
