I was confused by your original sentence. If your whole purpose is to be able to remove the oil pan, you only need to raise the engine up a few inches. You can do this by unbolting the mounts at the lower nut and using a floor jack. A 1/2" steel rod can pass thru the triangle opening in the K-frame to fit in a large hole in the bottom of the block outside the oil pan. Once off the mounts use blocks of wood to hold it up. Anyway, you are going big.
