I ran the MP .484 cam in a 383 Dart and it ran great but it was set up for it. It was a basically a stock 383 with the heads shaved for 9.5 comp and a mild bowl blend job. I had the Performer RPM intake witha 750 DP. I used 3.91 gears and a Turbo Action 10" tight 3000 converter. I loved the idle and the car ran a best of 12.31 @ 110. But I have to agree with everyone that it's not the best choice for your combo. It likes some gear and comp to keep some low end in it. I would want to use at least 3.91's in a Runner with the .484 cam and I would advance the cam to about a 104 centerline. Ron.
