why does the caddy ctsv

my friend just got a 2005 caddy cts-v with the ls6 block, very nice car, but why do they have such low horse power when compared to the c5 z06 ls6 engine? i have read on several sites that they dyno something like 320 to 330 rwhp ..anyone know what the difference is?

I think they are close, Maybe a little different cam?

Most of the 02+ z06 dyno numbers I've seen have been in the 350-360. That's much higher than 320-330

From 2004 and 2005, the CTS-V came with the 5.7 L pushrod OHV LS6 engine producing 400 hp (298 kW) at 6,000 rpm and 395 lb·ft (536 N·m) of torque at 4,800 rpm. The 5 lb·ft (7 N·m) torque reduction of the CTS-V vs the LS6 used in the C5 Z06, was due to the exhaust manifold that needed to be used on the CTS-V. From 2006 to 2007, the previous LS6 engine was superseded by the new 6.0 L OHV LS2 engine as used in the base 2005 Chevrolet Corvette. The new LS2 engine was rated at the same 400 hp (298 kW) at 6,000 rpm with the peak torque of 395 lb·ft (536 N·m) at 4,400 rpm. While both engines offer the same HP and torque specifications, the LS2's benefit was a wider torque band, due to the higher displacement it offered.

400 HP is still allot. I got a ride in a member's newer CTS-V with the 556 HP. That was fun
