From all the races that I was able to review the data ( maybe 10 races), the 427 cobra (s) always finished ahead of all the 289 cobra's. I did not include DNF's.

Absolutely the same results as I found in my own research years ago. The myth that the 289 Cobras consistently beat the 427's is just that - a big myth.

The truth is that the 289's won more races before the 427's came along because they enjoyed a longer period of factory support, while the 427 program never really took off due to focus in other directions (Daytona Coupe & GT40) and the changing face of racing itself that rendered open roadsters like the Cobra generally less competitive overall.

In the hands of privateer racers, when they were raced against each other, the big block Cobras with their greater power and improved suspension almost always blew the 289's into the weeds. The legacy of the 289 is that it brought home the championship trophies. The 427 just never really got the opportunity.
