Larry,
We were using a 600 cfm Holley. It does have vac secondaries. We tested it to determine if it would have any good characteristics for a street/ hot street setup. It certainly will not fit under the hood of my car and most other cars. The AFR were correct and it did not run lean. We tried to keep them at between 12.5 and 13 as that is what I have found works best for this engine from my experiences.

I have a feeling this intake is best suited for a engine that lives north of 5k RPM and stays there. It is crossed off my list of good street intakes.

Like to see pics of your intake design. How did it work on the street?
