I think you are sort of wondering about replacing your circa year 2012 computer with a circa 1950 mechanical adding machine here. It might be doable, with a lot of work, but why on earth would anybody want to do that? What you lose would be enormous, what you gain questionable, and the costs substantial. Sure, nostalgia for "the good old days" is nice and all, but really?
Nostalgia has nothing whatever to do with it. I am an engineer, not an art critic. The facts are that electronic injectors themselves are between ten and twenty times more expensive than mechanical injectors, while the HP pump and computer add insult to injury. The added complexity of the electronics add cost to both initial outlay and maintenance, and worse, lower system reliability.
The added performance is about 20% additional power and torque, most of which I can easily recoup by adding boost. With a manual gearbox and mechanical injection I have no need whatever for any electronic components, a significant advantage for a number of reasons. For example, I would not take the Liberty swimming even with a snorkel as dependent as it is on electronics. Advantage: mechanically injected engine and manual gearbox. I am willing to trade a slight loss of performance for improved serviceability, reduced maintenance costs, and improved reliability.

The slight coolant loss I was getting has gone; don't know whether it was leaking from the WP or leaking out the HG, but there was no sign of leakage around the WP, and some of the studs took up to a full turn to reach final torque at 130 FP. Given that and the large variation in removal torque on the old head bolts, I strongly suspected a (formerly) warped head. NOW that head is securely clamped to the block, and I seem to be losing no coolant. One less thing to worry about, which is why I am thinking about a manual gearbox. That will be one fewer thing again to worry about.
