After I fitted the upper cown attach hinge I went ahead and installed the engine mount. I torqued the bolts to spec, but I haven't installed the cotter pins just yet (it will come off again later).
With the mount in place I pulled out my hoist and put the engine in place. Getting those dynafocal mounts to line up was all kinds of fun, but I got it done. After I had the whole thing bolted in place I realized that I had the top and bottom bolts swapped (slightly different lengths). I undid the bolts and swapped them around.
