Engine Test Stand using K member?

I'm considering running my soon to be rebuilt 340 on a test stand before I install it in my Swinger which is under restoration. I've built a test stand for an air cooled engine which was a lot simpler and cheaper. I don't want to be working on the engine after its installed should any issues arise. Has anyone used the K member as part of the test stand. I'm wondering if its easier to bolt the k frame to a dolly than fabricate engine mounts. The only other issue is the expense of making a control panel. I would run at minimum starter relay switch, oil pressure and water temperature gauges. Perhaps there is something off the shelf I could use....haven't searched yet. I could use the rad I was going to install and temporarily adapt mufflers to the TTI manifold down pipes I'm planning on using. Ideas or suggestions appreciated. I have time for this build.
