Who else here is running a Low Deck 400 combo? I would like to hear what combo you are using, and what horsepower you are making. My combo is a 499, 906 heads, purple cam, old Holley streeet dominator manifold, 850 Demon carb, eagle rotating assembly. Never been on a dyno, but it's run 6.80's in my 3200 pound Dart, I'm sure it could run quicker but it's a bracket car so I don't lean on it. Let's hear your combos.
