Short answers, pulled from the story.
The Saturn C-8 stood as the largest member of the Saturn series rockets ever designed. Its first stage featured an increased diameter that held eight powerful engines instead of the usual five.
NASA announced on the 7th of September 1961, that the Michoud Ordnance Plant near New Orleans would build Saturn stages. Finalists included two government-owned facilities located in St. Louis and New Orleans.
The adoption of lunar orbit rendezvous in 1962 changed everything about mission planning. This new concept approved by NASA rendered the massive C-8 design obsolete overnight.
The height of the factory roof at Michoud created a hard limit on assembly capabilities. A launch vehicle with eight F-1 engines could not fit inside the building.
No Saturn C-8 vehicle ever progressed beyond the initial design process stage. Historical records show it remained a conceptual milestone rather than a flying machine.
