 Just bought a 312 and will be rebuilding it. Was curious about any badass cams that would sound good in it or any websites that offer sound clips? Betsy

Add this to what has already been mentioned. As a general rule and with all other camshaft specs being equal, reducing the lobe centerline angle on a given camshaft gives a rumpier sound. While the peak torque numbers can increase with a reduction in the lobe centerline angle numbers, manifold vacuum at idle will be reduced which can force some additional carburetor tuning to eliminate a hesitation that would not have been there otherwise. For these reasons CK and Charlie are both right in that there’s more to camshaft selection than just the sound. How the vehicle is driven, the transmission type, transmission gearing, and rear end gearing must all be taken into account when selecting a camshaft. When all those parameters are known, then the appropriate camshaft with the desired sound attributes can be properly selected. Generally a wilder camshaft will be more tolerable in a standard shift application than in a automatic transmission application. Where an overdrive gear is involved, then running at lower rpms must also be taken into consideration. While a 108° lobe centerline might work okay with a standard transmission, a 110° or 112° lobe centerline may be more desirable in an automatic transmission applications depending upon the stall speed of the converter. There is a fine balance between having a rumpy camshaft and still maintaining acceptable driving charactertics.
