Could be tight. You never know. Results will probably depend on whether you are racing against a high-mileage daily driver or not. The vettes were'nt all that powerful then, but they are still a good deal lighter than the bonnevilles.
If someone put a decent cam or rebuilt the carb on the vette, you'd be in for a race. If its something somebody kept in a garage all these years and did nothing to, it might be different. I've learned that with a carburated engine, stomping on the gas isn't always the best thing for a launch. Most of those old v8'* need to be finessed, at least in stock trim.
