I seen a pontiac ventura with a 455 run a 10.83 with a 600 vac sec carb that had no other work other than a jet change. So you reall don't have to worry about the carb being too small. You could slap an adaptor on and a throttle bracket and it would go down the road. Be aware that that type of adaptor doesn't make a real smooth transition to the manifold. What ever carb you use get the manifold that fits it.
