The meanest Camaro ever created is the 2012 ZL1 which was unveiled at the Chicago Auto Show last week, and which unfortunately will hit the dealership floor sometime next year. The 2012 Chevrolet Camaro ZL1 will develop 550 horses and 550 lb-ft of torque from a 6.2-litre LSA V8 plant which uses supercharging and intercooling and which will be linked to a six-speed manual transmission.
Were are we getting with all this ? Well we have some good news. For those who don’t want to wait until next year, SLP Performance is offering a tuning package based on the Camaro SS which will also bare the ZL1 name and promises 750 HP from a seriously modified 7.0-litre V8 plus a top speed of 205 mph.
The 2011 Chevrolet Camaro ZL1 by SLP will also be fitted with a 6-speed manual with power being delivered to the rear, and on the long lists on enhancements, customers will find an adjustable coilover suspension, Brembo GT brakes, a custom exhaust system, and 20 inch alloy wheels wrapped in Michelin XL Sport PS2 tires.     
Production for the 2011 Chevrolet Camaro ZL1 by SLP will be limited to 69 exemplars.
The complete list of modifications are available after the jump.
SLP Camaro press release :
After 42 Years The Legend is Back……and only from SLP!
The year was 1969, and the muscle car wars were in full swing. Each one of the big three
had developed their own version of the ultimate high-performance big-block engine.
Then Chevrolet unleashed the ZL1®, the most powerful 427- cubic inch engine ever released
by General Motors. Based on an exotic aluminum block, the ZL1® offered only the best
components from the L88 engine including a high-compression piston, high-flow aluminum
heads and intake, and a bulletproof bottom end. In all, only 69 Camaros and 2 Corvettes were
ever produced with the ZL1® making it one of the rarest and most desirable big-blocks ever made.
Now, in the tradition of that legendary ZL1® Camaro of yesteryear, SLP presents the 2011 ZL® Camaro.
Only 69 will be built for 2011; all with a 750HP Supercharged 427ci powerplant; and they’ll go fast! Literally.
