    usra bmod engine intake question

    I run a spec usra bmod motor and currently use the performer intake. Some guys run the weiand and I'm just wondering if anyone has info on which is better with the 4412 carb.

    Edelbrock. Friend bought a new motor from a high end builder and they dyno'd with both. Edelbrock was best with 4412

      Edelbrock has been best for us on the dyno as well.

        Stick with what you have. We dynoed both intakes back to back and the edelbrock was the winner. Eric

              hmm i was thinking about the wehrs WM10100 which moves the carb to the front. I was watching a CNC motors video and thats the one they use. No sure which one would be better. But from what they were saying they like the 10100 because under the g-force loads coming off the corners it helps all the cylinders have even fuel. idk
