This is the carb I ordered today

scroll down to the stage 7 dominator. I'm gonna use a 1/2 adapter and then stick a HVH 1" 4 holle tappered on it them the carb. These dominators are really supposed to like the HVH. I made 545hp atw's with the stock Demon. I'm hoping to get in the upper 5's with the dominator and the turtle.
