HOw much CID. If it is a 302 yes. Rumble is wonderful and I use to love it but those engines are not fast. . .what I mean is they are lazy to pull because the duration to make the rumble is intended to sustain POWER at upper rpm. What you can do is get a cam with say a 108 lobe sep and advance it to a 102. This will build cylinder pressure and give the engine a crisp sound. ..Snap.
