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$.

The Performer is an improvement over the standard
manifold, not only in weight savings but in
performance. It parallels the HP manifold and is
very close to the M1 dual plane. The Performer
RPM is a great manifold which extends the power/
torque range over the Performer, given the proper
cam is installed. The benefit of the RPM is that
you retain "some" low end power while gaining
power midrange and top end. For a stock vehicle
this may be a good manifold, but the single plane 6 times out 10, gets the nod when modified. The
Performer is considered probably a standard flow
while the RPM may be the higher flow type. Check
on this though, I may not be accurate. Good
luck with this.
