Part I
The 289 is all AC, the 427 was AC with some Ford input, it's all out there on the internet.

Production proved to be easy, since AC had already made most of the modifications needed for the small-block V8 when they installed the 2.6 L Ford Zephyr engine, including the extensive rework of the AC Ace's front end bodywork. The most important modification was the fitting of a stronger rear differential to handle the increased engine power. A Salisbury 4HU unit with inboard disc brakes to reduce unsprung weight was chosen instead of the old ENV unit. It was the same unit used on the Jaguar E-Type. On the production version, the inboard brakes were moved outboard to reduce cost. The only modification of the front end of the first Cobra from that of the AC Ace 2.6 was the steering box, which had to be moved outward to clear the wider V8 engine.

AC exported completed, painted and trimmed cars (less engine and gearbox) to Shelby who then finished the cars in his workshop in Los Angeles by installing the engine and gearbox and correcting any bodywork flaws caused by the car's passage by sea.
