I am assembling the engine from my '53 Buick Super. Had it machined, and am installing new pistons/rings/ bearings/etc. I'm using Lubriplate 105 as the assembly lube. After assembly, I'm sure the engine will sit for a couple of years while I work on the car's body, etc. Question is, should I prime the engine oil system before laying it up, or wait to just before I start it to prime it? Thanks.
