You need to sit down in front of the computer and spend time on the Corvette websites. There is so much online for the Corvettes that all your answers will be addressed somewhere there online. If you have popping sounds, my first thought would be "Did you put the distributor back in correctly per the firing order ?" It sounds like you are out of firing order so recheck it. Then search the Corvette websites and also look at www.Chiltons.com before you go any further.
