They tune great, they run great and they look great.

The four idle adjustments and the separate outlets for manifold and ported vacuum are a plus.

I have a 650 on a SBC and what a difference in performance. I have seen decussions stating that they flow more air than a Holley the same size also.
I was cheap and used a Holley on the Cobra because it was collecting dust on the shelf. It is only a Crate Motor, so I am OK for now.
I am sure you will be pleased with it's performance on the Dyno.
