Engine & Drivetrain:
* Performance Upgrades: The 305 is a decent starting point, but it's not known for high horsepower. Options include:
* Intake Manifold: A performance intake manifold (Edelbrock Performer RPM or similar) will improve airflow.
* Headers: Long-tube headers significantly increase exhaust flow, adding horsepower and torque. Expect to need new exhaust pipes to match.
* Cam Shaft: A performance camshaft tailored to your desired driving style (street or race) will alter the valve timing for more power. This often requires other upgrades (springs, lifters, etc.).
* Carburetor (if applicable): If you have a carburetor, consider a performance rebuild or upgrade to a larger, more efficient unit. If it's throttle body injection (TBI), consider upgrading to a more efficient system or even a carburetor conversion (more complex).
* Air Cleaner: A cold air intake system will supply cooler, denser air to the engine, increasing power.
* Ignition System: Upgrading to a performance ignition system (e.g., MSD) can improve spark and combustion efficiency.
* Exhaust System: A free-flowing exhaust system (beyond the headers) will help get the spent gases out efficiently.
* Higher Compression Pistons: This is a more involved modification requiring machine work but yields significant power gains.
* Roller Rockers: These improve valve train efficiency and reduce friction.
* Transmission: A stronger transmission (if it's not already) might be needed if you significantly increase horsepower. Consider a performance rebuild or even an upgrade to a stronger unit if you plan on aggressive driving or racing. This includes the rear end. A posi-traction differential is also a wise upgrade if you want better traction.
* Cooling System: With more power, cooling becomes critical. Consider an upgraded radiator, electric fans, and perhaps a better thermostat.
Suspension & Handling:
* Suspension Upgrades: The '82 Camaro's suspension is relatively basic. Upgrading to better shocks (e.g., Koni, Bilstein), springs (lowering springs for a sportier look and handling, or stiffer springs for better control), and sway bars will dramatically improve handling. Consider polyurethane bushings for reduced flex.
* Brakes: Upgraded brakes are crucial, especially with increased power. Consider performance brake pads, rotors, and potentially a larger master cylinder for better stopping power.
Appearance:
This is largely subjective, but options include:
* Wheels and Tires: Performance tires mounted on aftermarket wheels will improve handling and grip.
* Body Modifications: A new paint job, spoilers, ground effects, etc., can significantly alter the car's look.
Important Considerations:
* Budget: Upgrades can range from inexpensive bolt-ons to thousands of dollars in engine work. Set a realistic budget before starting.
* Mechanical Knowledge/Skills: Some modifications are relatively easy, while others require professional help or significant mechanical expertise.
* Reliability: Aggressive modifications can sometimes reduce reliability if not done correctly.
Start with smaller, less expensive upgrades (intake, exhaust, suspension) to see how much improvement you get before investing in major engine work. Research specific parts and compatibility for your particular 305 engine before purchasing anything. Plenty of online communities (Camaro forums) can offer advice and guidance.
