Thats close the the 383 we ran in my sons Dart. It had stock pistons with 906 heads I milled and bowl blended and got 9.5 comp. I used the RPM intake with a 750 DP. But I used the MP .484 cam and ran 3.91's with a Turbo Action 10" tight 3000 converter. I had the cam on a 104 centerline and it ran great. The Dart weighed 3550 with my sons 190 in the car. On G/60-15 McCreary's it ran a best of 12.31 @ 110. It really was a nice running combo. Yours sounds like it will run good. This is my sons Dart and it has the 400 in it in this pic but we used the 383 in it first for years. Ron
