Did you have to bore or radius the manifold inlet so that the throttle plates would open or did the carb fit without any modification?
If you didn't have to do any mods then probably a 215 carb especially since it came with #47 jets.
But due to the size of the 215 carb size you are only going to only gain a little more airflow than 94 carb.
