Chevy did a 2000 ZL1 Camaro concept car that would be worthy of the Yenko stripes. How about a 2002 ZL1 COPO? They are making the block again but I don't think the GM lawyers would approve.
The 2000 ZL1 info......
"At the heart of a laundry list of updated ZL1 modifications is the powerplant: an 8.4-liter aluminum-block pushrod V8 making a foot-stomping 770 horsepower at 6900 rpm and a raucous 683 lb.-ft of torque at 5200 rpm. Transfer of power comes via a five-speed manual transmission and a three-disc hydraulic clutch setup.
On the numbers side, that potential is realized in a 0-60 mph time of just 2.7 seconds. The ZL1 runs the quarter-mile in 10.410 seconds (137.19 mph) and has a top speed in excess of 230 mph."
