[Brooklyn-427]

Ultimately AC would of sourced a fresh engine for the ACE eventually, Ford V8 or not ... devoid of Ole Shel who knows! They must of realised that times had changed, Jaguar and Healey had moved forward and were taking a sales lead with cars like the E type and 100/6.
TVR may have been a option for Shelby, they was more of a company that had the direction he was looking for.
Overall the Ace was the traditional British sports roadster, 289 car is car that became the iconic 427 .. History is written and cant be altered or changed.Its the chicken and egg.
