RPM Airgap vs. non-Airgap?

Dave you have a very nice build there. Hot street and weekend warrior setup. The test would be better if you could only change out the manifold only cause the additional carb change may have an affect also that makes the manifold look better or worse is you know what I mean. I understand it's more work though.

I'd say you have the paramaters covered pretty good. At the moment I can't think of any else.

BTW: Have you ran your car with your current setup?
