Edelbrock LD340 WTH?!?!?

that big runners are not as effective as smaller runners, hence the smaller CSA of the Perf intake.
This is a CID needing it or not. On a dual plane, I agree. We have seen this before a few times. The newer intake has a better runner and does t need to be large in size. This is why I think it works so well on the street. The air and fuel have an easier time moving into the head and cylinder. Less turning corners closer to a line of sight.
