New street demon carb.
I have one ( the composite body one) on a Stock 98 5.2 magnum with an m1 dual plane. (74 Duster). Runs alright. Have only used it for street cruising and 1 autocross. Drove to Fall ball at Indy. Air door is easy to adjust. I tightened mine slightly to delay the secondaries. I have no 1/4 mile data and do not run an 02. Tail pipe is on the clean side and it does not seem rich(exhaust does not stink). So far , I like it.
