I've run 383s for years and my favorite intake back in the day was an Edelbrock DP4B dual plane. My mostly stock motor ran great with it. If you don't care about period correct the Edelbrock Performer RPM is even better. When I built the motor I stepped up to either an original Torker or six pack setup. You'll be very happy with either the DP4B or RPM.
