Best low profile 383 dual plane aluminum intake?

Nothing wrong with the performer rpm, it’s a great intake. the regular performer is basically a door stop. What number is on the carb. It won’t be a 750 more like 500 to 625 cfm if this is a factory carb. Do u use the choke now, if not u could take it off but it is recommended to have a choke as u have much easier cold starts. Is the choke run by a cable or from the choke well in the intake. Kim
