options for first start - oil priming Options

[Optimusglen]

Hey all, my project is coming along and this weekend I will probably try the first start.

It was a rebuild down to the shortblock, 1911 with dual Webers.

I've heard of a few methods for priming the oil chambers and wanted to see if there was a preferred method you guys use.

Option 1: disconnect fuel pump and just crank it over until the oil pressure light goes out.

Option 2: disconnect fuel pump and remove spark plugs and valve rocker assemblies to reduce load on the starter and crank. Turn over until oil pressure light goes out.

Option 3: fabricate an oil can that can take air pressure, hose comes out and connected to where the oil pressure switch goes. Pressurize the can and push 2 qts into the engine, add the rest of the oil to the filler.

Any other methods?
