Cranks but wont start.
Show the distributor cap with #1 plug terminal identified, and confirm that the firing order is correct.

260Z Firing order
You need to show the wires to the distributor to know if the firing order you used is wrong or not.

240Z Tach Wiring After 123Ignition Install
Couldn't really tell from that diagram which is positive and which is negative. Why would negative or positive matter if it's just sensing power? (Edit - actually I don't really understand how that device works. Maybe it's "sensing" sparks? Current flow? Whatever it is, the positive side might work the same. @SteveJ @Captain Obvious ) If you have another load on the negative terminal of the coil that could screw up your tach signal. I'd disconnect that before you get too far along and see if it starts working. I don't know if the condenser will help you with that scheme. If it fixes the tach problem try using the positive side of the coil for the power signal. Edit - actually don't try this. It might be a direct short, depending on how the device works.

240Z Tach Wiring After 123Ignition Install
Is it an inertia switch? It looks like it supplies power to the coil also. Have you disconnected/unplugged the factory ignition module? While you're down there you can also test continuity back to the coil negative. It's a branched circuit, one to the ignition module, one to the tachometer, one to the ECU. The condenser/capacitor on the blue wire is easy to setup. That's what worked on mine, with a GM HEI module. Any condenser from an alternator will work. The wire to the capacitor goes the coil negative, the capacitor can be mounted on the ground point on the manifold, nearby. It's a cheap quick test if you have one laying around. Won't hurt anything.

240Z Tach Wiring After 123Ignition Install
By "tach sense" wire you mean the blue wire that heads back past the ignition module, right? What is this "fuel safety relay", and how is it connected/wired? That would be new to the system. The tachometer seems sensitive to the signal on that wire. You could disconnect it for a test and see what happens.

R180 Diff Plugs 240Z
Did your family do all of the service or did you take it to a shop or dealership for service? Does anyone in your family own a Subaru?

R180 Diff Plugs 240Z
Pickup trucks used the 4.11. 240Z's did not come with a 4.11. Nissan might have went with the recessed plug for looks. They even built a special shield just to cover a bolt head in the back on later cars. On a truck an ugly square head is not such a big deal. But, Whitehead is just using the same R180 picture for all of his R180 listings. So, who knows what's what there. https://whiteheadperformance.com/product/nissan-oem-3-54-r180-diff-differential-used-datsun-240z-260z-280z-280zx-510/ https://whiteheadperformance.com/product/nissan-oem-3-70-r180-diff-differential-used-datsun-240z-260z-280z-280zx-510/ https://whiteheadperformance.com/product/nissan-oem-3-90-r180-diff-differential-used-datsun-240z-260z-280z-280zx/ https://whiteheadperformance.com/product/nissan-oem-4-11-r180-diff-differential-used-datsun-240z-260z-280z-280zx/ 78 280Z with bolt head shield. Whithead's label implies it's just a stock photo he picked up somewhere.

Rust Advice 78 280z
What procedure are you using to adjust rocker arm clearance (lash)? If it ran fine before then your work must have done something to change something. Are you rotating the engine and camshaft as you measure and set lash to be sure that each lobe is on the base circle? Seems like a very loose rocker arm is the most likely possibility for that kind of noise and the work you did, considering that it "ran fine" before. Don't really see any other moving parts in the engine that you touched that could cause it.

Rust Advice 78 280z
That noise still sounds pretty solid. Like objects with large mass. I'm changing my guess to rod bearing. Or not. Can't really tell. Your videos are at idle. What happens if you rev the engine?

260Z Tach Connector
Search "280Z tachometer" and you'll find pictures of the plug out of its socket. Might give you the confidence to pull harder. My tachometer used to stick when the weather got warm. The capacitive discharge ignition systems are well-known for causing tachometer problems. MSD, Crane, etc. Might be worth your while to reconnect the old ignition module and see if the problem goes away.

Somebody stuck a fill plug in the drain hole, probably because the socket type drain plug is a pain to remove. Browse through these listings, below, and you'll find a few pictures of the original setup. I don't think that Nissan did any "one-off" plug arrangements. You should post the replacements that are not of this type just so that people can see them. Might be an aftermarket guy offering an improvement. https://bringatrailer.com/datsun/240z/?q=240z

COVID-19
One of the great ironies of the situation, and one of the reasons that I believe in the vaccines, is that any pharma company that released a vaccine that damaged people would get destroyed in the stock market. The spotlight is so bright that they would not be able to BS their way out of it.

The point was that FDA approval is not worth much. I think that overall we got got lucky that there are good individuals in these various bureaucracies that know how to work within them to get good things done. But eventually the bureaucracies will get so corrupted that nobody can get anything done. It's already happening in branches of government. Let's hope that some rebuilding happens after this close call. And be thankful for the people that pushed the working vaccines through. If you believe the reporting, they actually work, with no side effects. I feel fine.

The Black Box. Probably would have had to get a "Q" clearance. Q used to mean just a certain level of security clearance. I assume that "Q", whoever Q is/are, has/had a Q clearance, hence the moniker "Q". Anyway, you missed out on the whole Boeing culture in the PNW. Work hard, get laid off, collect unemployment knowing that the cycle will repeat. I had some friends in the Boeing world. No offense Racer I don't know if you're an engineer or not. But there really is a "Boeing way of life" out here.

The FDA is not really what people think it is. It suffers from serious "mission drift". It needs a major overhaul. https://www.reuters.com/article/us-health-coronavirus-vaccines-fda-exclu/exclusive-top-adviser-steps-aside-from-fda-covid-19-vaccine-reviews-over-potential-conflict-idUSKCN26E3IW https://ethics.harvard.edu/blog/risky-drugs-why-fda-cannot-be-trusted

Some work with a meter and a battery, should do the job. Measure resistance and direction. A fun project.

280z Bosch Relay Correlation? Stock Relay vs Porsche Relay
There's a 120 and and a 121. The 121 says "Jetronic", the 120 doesn't. Wonder if diodes/resistors is the difference. I know that their typical 5 pin relays come in different flavors. Same basic functions, just some have a few extra parts inside. Usually they show it on the cover, but these don't. Edit - the 121 has 13 pins vs 11 for 120. Not sure how that affects things. Haven't studied the pin diagram. https://www.amazon.com/Bosch-0332514121-BOS0332514121/dp/B006NYJ328 https://www.amazon.com/Bosch-Automotive-0332514120-Relay/dp/B004Z0W1C6
