I'm messing with camquest and was wondering if the performer intake for a 383 would be considered standard flow, high flow, or max flow dual plane intake?

Anyone had good luck with this intake? I use it on my sbc and haven't had any problems. I just want to have a dual plane intake that takes some weight off the engine. I removed the stock intake and that sucker is HEAVY! I'm young and thought I was gonna get a hernia.

Found a guy nearby selling one in good shape for 100$.
