Prestart engine lube....does this work?

[YerDugliness]

I am considering a rebuild of the 1989 5.0 HO engine in the Cobra, and in the interest of longevity I would like to consider a prelube system to be used before starting the engine. In the past, understanding that a large part of engine wear is induced during the first few seconds before the oil pump gets the oil circulated throughout the engine, I have disconnected the coil wire from the distributor and then cranked the engine until oil pressure registered on the gauge....after which I would crank the engine for another 5 or 10 seconds, then reconnect the coil wire and start the engine. I don't know if this worked or not, but it seemed better than cold-starting the engine.

I know that this product (an Accusump oil accumilator) would probably be better, just wondering if I have been kidding myself for all these years that I might have been helping avoid dry-start damages:

What do you all think? Were my efforts effective? I was more worried about the main/rod bearings than the pistons....figured that until the pistons got up to operating temperature, the clearance between the skirt and the bore would be adequate and that there would be plenty of oil in that area by the time the piston got heated up.
