The Z/28 has the LS7 or 427C.I. or 7.0 Liter engine (which ever designation you would like to use)with dual mode exhaust, while the new C7 has the new LT1 or basically a LS3, 6.2 Liter with direct injection and variable valve timing with dual mode exhaust. The LT1 is making 460 HP and 465 Torque in the C7. So that's why the Z/28 sounds better cause the LS7.
