I have this cam in my '72 Cuda 340 and it is a great street cam with decent mileage and performance. My car has 3.55 gearing and I'm getting 14-15 MPG on the highway and have run a best of 13.90 at 100mph with no traction (60' times of 2.15).

Does anyone know how this cam compares with the voodoo 60403? I'm looking to get more power but don't want to sacrifice too much in the way of mileage.
