I did that with my modified 235,but I have no pics to show. It was pretty simple though,completely made of 2x2's and 4x4's and sat om my garage floor.I made two 4x4 pieces that mounted to the front engine mounts and tied them together with some 2x4's.Across the rear the block sat on a 4x4 with some 2x4's bolted where the transmission would bolt. It was very stable beyond 2500 rpm.I used the stock radiator in its frame and used a plastic gas container to the fuel pump.The battery sat on the floor with normal hookup to the starter thru the stock ignition switch mounted on a plywood panel with an oil pressure gauge,water temp gauge and an old tach I had.Took an afternoon to assemble and worked just fine for cam break in and timing & carbs adjustment.
