Looking for a carb to put on a 360 380 mopar performance magnum crate motor. Both carbs are about the same amount of money (Holley $395 vs. Demons $399)., but which would work best for a street driven vehicle, which will see the track once in a while. I'm kinda leaning towards the Holley (adjustable vaccum secondaries sounds like a good deal,plus 770 cfm.) I'd put all the details about both carbs but, i'm kinda in a hurry. I've never used a Barry Grant carb so my knowledge about them is limited. This isn't my engine but a friend who has the basic know how when it comes to engines. Once this carb (which ever that may be) is set up it will most likely stay that way.I know there are die hard Barry Grant as well as Holley guys out there, so lets kept it to a civilized discusion.
