Yeah I've had guys tell me that the Dominator works better on a 4150 intake due to the "venturi effect". Not exactly sure what that means but it didn't work on this combo.

For comparison the TF intake with a 4150 carb was 10 hp better than the unported M1 4500 intake with the Dominator carb. The Wilson intake added a bunch of power over the unported M1 but most guys aren't going to spend the bucks to have Wilson re-work an intake that much. So for the average bracket guy the best combo appears to be the TF intake with a good 4150 carb.
