Here is a comparison:

With the intake/exhaust, he's probably got the same HP as you (approx), and more torque (even at stock), and if the Z28 is a manual - it weighs about 150 lbs more than your SRT6 Coupe (assuming they are both coupes).

0-60 times are fairly close too. SRT6 = around 5 seconds, Z28 = 5.2 seconds (stock).

Should have been pretty close. Throw a Renntech pulley/ECU upgrade on there and then wear him out repeatedly - if that's your thing.
