340 Cam Compatability

It will be too much. I would stay away from the Xe series, or similar fast rate cams if you want the sound. But they will be down on torque with 3.23s that will be felt when you drive it. Personally, I cant imagine buying a cam strictly for sound. But that's just me. There are also some newer cams that tout that "oldschool" (poor) idle characteristic too. So I would shop around.
