A V8 will never sound like a V12, and Lucas is just the electronics, that can easily be changed and eliminated
then modify the engine for power, stock is 300+hp, and 400 shouldn't be hard to come by. Keep in mind the jag puts down over 350 lbs of torque, I believe the ZO6 is 385 lbs, so it is in the same ballpark, and the GM engine has been done too many times, who do you know with a V12 Chevelle? I want my own car, not a copy of someone elses
