i think its kinda weird to have the intake for sell with no dyno chart or HP rating or anything.for all we know u could lose $550 and 100 hp.i started a tread on this a month or so ago and it wasnt for sale then but no dyno charts then either.edlebrock has had charts on theirs from the beginning.
Have not heard much on this one or the edelbrock victor coyote manifold... FWIW I have heard this Holley intake isnt even made by Holley, outsourced to some chinese car parts mfr...it suspiciously looks a lot like some of the garbage chinese knockoff 'custom' sheetmetal intakes I've seen out there for LSx applications. I truly hope that is not the case, but it would not surprise me either.
Here is a chinese knockoff for LSx platform
Looks OK from the outside, but the inside is another story
Runners look legit
