I have a magnum based 408 in my dart. I'm hoping to start installing my Holley Sniper EFI pretty soon. It's an 11:1 compression engine with some edelbrock magnum aluminum heads. The cam is a Hughes engines .571/.576 lift and 234/238 @.050. It's a street/strip car, never gets used for daily driving. I'm currently using a street demon carb bolted to an Edlebrock airgap intake. I also have a Magnum M1 single plane on the shelf. What do you guys think the best intake choice would be? I will probably try them both eventually but I have to remove the intake to drill/tap a hole anyways.
