Hey i saw this same argument in either MotorTrend or Car and Driver like 2 years ago. Car and Driver called the Viper the "New American Sports Car". The numbers for a corvette according to the 2000 Autoweek buyers guide is a 0-60 time of 5.4 seconds. The Vipers was 4.2 seconds. top speed on a stock Viper is limited by a chip to 176, so it can not go faster than 1765 if it is 100% stock, but without the chip it can go at least the 192 MPH seen in MotorTrend. The average Viper engine lasts about 100,000 miles. The reason that it is that low is the fact that all of them are going to be driving the engine hard and over revving it. My engine, when unloaded revs very fast so i can imagine how fast a Viper's would rev, and therefore probaly be over revved more than a few times. If they are taken care of, and not pushed hard or over revved, there is no reason for the engine to last at least as long as a vette engine, if not longer.
