I admit it- I am still relatively new to this, so I have a simple question. I have read that my mustang may not like it much if I were to install a cam, for example, a ford racing E303. If I were to install the cam, would I have to take it to a tuner to make it run right? I am on a bit of a budget and am still in the planning stages for now. My mustang is a 94 GT, mostly stock as far as engine mods go, just an MSD distributor and Blaster coil sparking splitfire wires and NGK iridium plugs.
