What cam would be best for my 94 mustang GT?
 

I am going to be getting a cam for my 94 mustang in a few week and was wondering which one i should get. Its an automatic. My car has a few bolt but that's it. i was thinking of getting the lunati street avenger roller tappet cam, but i want to hear other ideas, and how much of a gain in horsepower and torque i can expect.
