Fresh Start After 15 Years

[Feldsine]

Going to start a freshly rebuilt 350. I bought this truck (71 C20) from the original owner, and he had put about 10 miles on the engine before parking it for 15 years. I pulled the dipstick, the oil was so clean I could barely see it. I'm going to change it anyway before starting, as well as the radiator water.

Questions are:

1. I would like to prime the engine oil. I read elsewhere that I would get an oil priming rod and spin it with a drill, however, this might or might not get oil through all the passageways, lifters rockers and cam. Is there some detail that I need to pay attention to when getting the rod?

2. I'm planning to change the oil and radiator water before starting. I'm not really wanting to get into the tranny. Is it ok to run the tranny enough to get it to an oil change shop to change it, or is that critical enough to change before starting? I don't have a good place to work and it would make a mess.

3. I bought a can of "SeaFoam Spray". It was suggested that I spray this into the spark plug holes to lube it up, and crank the engine by hand a dozen times or so before starting. That sound good?

4. Got most of the gas drained. Figured I would add about 5 gallons, and just before starting, and after oil priming, with the plugs still out, I would crank the engine till good gas started coming out the end of the line. Then hook it up and go for it. There is a filter inline by the tank, I figure I'll be changing that a few times pretty quickly.
