400 B Block Strokers

[70Dart499]

Lets hear some info from those of you running, 400 B block Stroker motors. I have a 499, in my Dart that was in the car when I bought it. I have steel heads, and a Direct Connection Purple cam, with Holley Street dominator intake and 850 Demon Carb. Other than that I dont know too much else about the engine since it was built and in the Dart when I bought it. Just wanted to start this thread to hear what combo's everyone else is running on these motors. I love the motor though, makes tons of power at low RPM, so its a great low maint. Bracket Engine. My best ET so far is a 7.15 in the 1/8th and that was on a so-so track in 93 degree weather.
