I did the shade tree things as well when I changed my oil pan gasket. And doing this requires the engine not only to be supported, but lifted 6-8". I used a 4x4 that was out back of the shed forever. Cut it to sit on the strut towers, but fit between them. The leftover part was notched out to fit over the first support and rest on the radiator support. I positioned everything and drilled two holes to line up with the engine support brackets. I used some long eye bolts to support the engine, and then crank on them to lift it up as I jacked it up. Worked perfectly for what I needed to do and cost me $0. But it can be made with whatever you have laying around. The engine is not that heavy.
