With its closed center cross member, pulling the engine and transmission together is the only realistic option unless you can do everything that you want to do by removing the cylinder head and oil pan (a project in itself given the V-shaped front axle radius rod(s) beneath the pan interfering with the pan's removal). Snyder's has all the gaskets you will need. I recommend that you rebuild the oil pump while you have the oil pan off (again, Snyder's has what you'll need). Both the rod and main bearings are poured and machined babbitt, not insert and hopefully all remain within specification. Given your engine number, it will likely not have the later counterbalanced crankshaft (unless the original was replaced along the way), which you might consider if you have to have any of the bearings re-poured and machined.
