The ABSOLUTE FIRST thing to do is put a camera in EACH cylinder to asses the rust. Rent one if you have too. Or hire someone that has one. Oiling the walls may cause the plugs to not fire. Instant start is extremely important. Our 78 Royale sat next to a corn field for 20 years to the month. Hatched a fuel can with an electric pump to the carb.. Turned the pump on to fill the carb. Pulling the distributor to run the oil pump to get oil on the lobs is a waste of effort. NOT happening. Cam bearings will still have some oil on them anyway. The cam lobes are lubed from spray from the crank. NOT the cam bearings. And the cranks not spinning. It's extremely important to not take a chance of not having the timing correct. With spark, and fresh gas. It will start instantly. If the walls have rust on them. Pull it down. Or. Put oil on the walls. Start it up. Then are you going to trust that engine 400 miles from home. When I got my 403 started. Started just like I turned it off 5 mins before. Bob Dunahugh
