Which intake is better Eddy air gap or M1 dual plane for the magnum?

The MP dual plane M1 is a really good unit but it isn’t 11 second time zone good. That M1 is excellent for general purposes. The real Performance game starts with the Edelbrock RPM and will handle 90% of what people are doing with there car.

We have even had a few members run the Magnum RPM vs the MP Magnum single plane M1 and declare, with time slip proof, that the Edelbrock is better and quicker in the 60’ & 1/4 mile.

I think it was member UOP that ran low 11’s with it and the test between intake manifolds as well.
