302 Crosswind Air Gap intake

I am collecting parts to Add some Claws to my 68 Cougar.

I know its not a Stang, But the same motor.

I have been looking at CNC Motorsports Crosswind Manifold
on Ebay for 150.00
They say ist good for 15-6500 rpm and Ilike the satin finish one.

Does anybody have one they are using?
Or Know if is any good?
It will have a 600 Holley sitting on top of it.
Just rec the ceramic coat longtube headers.
Mild Cam and removing the stock fan.

Thanks, PB
