Engine/trans mechanical restart procedure? After long hibernation, Searched...nothing found Options

[JeffBowlsby]

What procedure should be followed to restart a stock engine that has been sitting a while...like 10 years or more? Just the mechanicals, Not FI, Not electrical etc.

Here are my thoughts, what else should be done?

Engine
Drain engine oil, install new oil filter
Flush crankcase with 2-3 quarts of Marvel mystery oil, drain
*check for internal corrosion
Fill crankcase full of Marvel oil, let soak for at least a month (How much Marvel oil will fill the case?)
Drain Marvel oil, install new oil filter and fill with motor oil
Replace pushrod tube seals, valve cover gaskets
Hope that rear crank gasket does not leak, replace if req'd
Check for leaks, repair leaks
Check/adjust valves

Transaxle
Drain trans oil
Flush trans with 1-2 quarts new oil, then fill
Hope front trans seal does not leak, replace if req'd
Check for leaks, repair leaks

*I may have access to a borescope from work that may get me get into the gas tank, cylinder chambers and any other orifice to check for internal corrosion, cylinder scoring etc and will do that if I can borrow the scope for a weekend.
