Need to Bolt-on More Power?
If you just can't get the power you want by bolting aftermarket components to your engine, there is the option of a power adder. Nitrous oxide injection kits are easy to install and can improve power dramatically. Be careful though, power adders such as nitrous oxide, a supercharger, or a turbo will quickly find the weakest link in your engine! Parts like forged pistons are usually a good idea if you plan to run nitrous.
Ignition
If your Mopar was built after 1971, then you're lucky enough to have one of the best factory electronic-ignition systems ever built. Even so, increases in performance can be had by simply adding a more powerful coil or a more aggressive ECU to your existing ignition system. Older Mopars equipped with antiquated points-style ignition will always benefit from the installation of electronic ignition. For applications with increased cylinder pressure, or if a power adder is used, a high-energy coil and good electronic ignition is mandatory. Several companies manufacture ignition systems from individual components to complete kits. Along with improved performance, upgrading the ignition system nearly always nets better economy and enhanced reliability.
Don't Forget the Rest
Remember, making more power means the rest of your car will need to be upgraded as well. Your fuel system will need to deliver more fuel; your cooling system may be taxed and need to be upgraded; and to take advantage of that bigger cam, you'll need a looser converter and, quite likely, steeper rearend gears. Since a more powerful engine accelerates quicker, you'll probably need to upgrade the oil system as well. It's not the individual components but the complete package that makes a true performance car. If you're unsure about what parts will work for your application, we encourage you to call one of the many manufacturers' tech lines for assistance. By paying attention to details and using an effective combination of parts, you can have your small-block-equipped Mopar running with the big-blocks in short order.
