We use a 750 DP on my sons Dart with his .030 over 400 and it works great. He uses 3.91's also and even put an 830 DP on but it ran no faster with the 830 so he went back to the 750 DP which works great for him. Just a standard 750 DP we tuned. It has run 11.40's at 117 and its just a mild 400 driver. I like the 750 DP for mild street cars. Ron
