An engineer who worked with Edelbrock back then admitted this fact a few years back on another forum.
Weiand's Accelerator and Holley's Street Dominator are also in this category.
I heard similar comments from a Holley R&D guy several years ago. He also said something very interesting: His dyno tests showed that high rise dual planes, like their Weiand Speed Warrior and Edelbrock Performer RPM, give up virtually nothing on the low end compared to a low rise manifold (like Street Warrior and Performer) when used on a 350 or larger
. But they start making more hp at mid range all the way up to 6000 RPM -- the best of both worlds.
I like the Weiand 8120 Street Warrior for a street 283. It's a much newer design that the Edelbrock Performer and its cousin the Performer EPS, which is based on the Performer.
