GM cubic inch limitations

[Keith Tedford]

GM had plans for the 454 in the Camaro. The parts books were printed up for it. Insurance was one of the big reasons I would think. No insurance. No car. Pretty basic. People who could afford a Corvette could also afford the 454 and the insurance. If people wanted a 454 and couldn't get it in a Camaro, they would buy a Chevelle. I believe the Chevelle was cheaper to insure back then as well. GM would already know that this was the last year for the hipo cars so that may have had something to do with the call as well.
