As a matter of fact, our stage 1 or II modified “keg� intake will make more power than the stage 2 M-1, 2-Bbl because of their greater airflow. However, the M-1 2Bbl will “feel� stronger than the modified “keg� and accelerate you faster from a stop until the lack of flow reduces their top-end power (approximately 3500RPM). What you need is a manifold that has the small plenum volume like the M-1 2Bbl and the flow of a ported “keg� or better. Read on!

In the write up about thier modified kegger they write:

The Mopar Performance Magnum M-1 intake is basically a carbureted intake with injector bosses and is designed for non-roller, flat tappet or roller cams with power bands from 5500 RPM and up. The runner length is barely 4.75" long -- much too short for hydraulic, roller cam power bands, which are generally below 6000 RPM. If you plan on only racing at the drag strip with lots of gears and stall--this is the manifold. If not, be careful or you'll lose your entire bottom end and mid-range torque.

Who knows. Hughes is a good company, and I have talked to them on the phone quite a bit. They know what they are talking about, butI have heard that they have more experience dealing with carberated race cars more than anything.

I don't live there, so I can't say with 100% certainty, but I think Ca has a pretty stringent visual inspection. Anything on your motor, from the intake all the way through to the exhaust, has to be stock or otherwise have a carb exemption number. I know the law in Va. really just pertains to Cat converters. If your car came with one catalytic converter, then that's the way it has to stay fo the life of the vehicle. I just ran into this when calling 30-35 exhaust shops within a 50 mile radius of where I live. I wanted to get true duals with two cats goin into an x. Nobody would touch it. 25 grand for the shop, 5 grand for me, impound of the vehicle, etc. etc.
