That was cool! I have a '46 Chevy pickup with the 216 babbit beater that I re-built. Rod dippers, babbit rod bearings, with shims. Wierd distributor that rotates in whole instead of the points plate, and lots of rod knocking. The speedo will turn red in it's range at 50 MPH. That is where you are over reving the engine and doing damage. You just take it easy with the old girl. They run about 14 pounds of oil pressure hot going down the road. The main bearings are the only pressure fed crankshaft bearing. The rods have a tin cover with a dipper on it. The top of the oil pan has a tray that sets there with troughs that have oil in it for each rod. As the rod swings by, it scoups up oil for the rod cap and crank journal. If it gets to knocking, you remove a shim from the cap and tighten them up. The rocker arms rotate on a rocker tube which is fed by the oil pump. When the oil drains down from the head, it actually fills all the trouphs. You don't run too thick of oil. I love the old beast. To remove the the bell housing from the engine, or pull the engine, you have to reach up inside and remove the clutch, pressure plate, and flywheel while bolted together. That means you need to rotate the engine. Real fun if stuck or blown up. The Willys Jeep flat head Super Hurricane six was the same way. That design , I don't like. Now I have to share the company slogan for their new six cylinder overhead valve engines: "A Valve In Head, Means Ahead in value"
