Jeff,

Lets see. You are going to have a P-40 warbird with inverted engine and the airplane is likely to have retracts. If it is like most warbirds it will not glide. And you are considering an engine known to be finicky and require fiddling. Unless you are an expert at dead sticks and the sometimes repair that happens without power you might want to rethink the choice of engine.

Some here have been tuning engines for fifty years and can make anything run. Some are likely to be like one of my friends who fly’s so he can build. At minimum consider finding a less fragile airplane to work out the engine problems because there will be issues. Fourteen pages of conversation about the engine should be a warning.
