I did not get mine from Mbaird, but I do have one and will be installing very soon. I find I am using the car slightly differently than I thought I might, seeing a lot of highway usage. With the 3.23 gears and 4 speed I believe the dual plane might be a better fit. With this swap I am pulling the 950cfm 4150 carb with the Victor W2, replacing with the dual plane and a new AVS2 800. I will post results.
