the 454 was the most powerful production engine of it's time. No other motor from that era had the kind of powere that the LS6 motor did. Stock from the factory the Chevelle LS6 was faster than the '69 Daytona, '69 Charger, the '70 Challenger, etc. all of which is really beside the point, the fact is this is a comparison of the motors and the stock 426 saw numbers ranging from 370-425hp and 490lb/ft torque. The 454 stock figures were 450hp and 500lb/ft torque. There were a couple Heni's that got under the Chevelle's time, but they weighed atleast 500lbs less to do it. And then I just pull out the Corvette ZL-1 numbers 3.9sec 0-60 and a 10.5sec 1/4 mile and the '69 Super Yenko Camaro that did a 3.8sec 0-60 and 11.9sec 1/4 mile, both of which had smaller, less powerful, engines than the 454 LS6, the deciding factor being weight of the vehicles.
