How to Increase HP on the 1987 Monte Carlo SS
Performing bolt-on performance modifications will increase the horsepower on your 1987 Monte Car SS. The stock 1987 Monte Carlo SS features a 5.0-liter V-8 engine that produces 180 horsepower. By replacing the engine's stock intake and exhaust components with aftermarket performance units, both horsepower and engine efficiency will increase. As an additional benefit, bolt-on modifications can give your Monte Carlo SS a customized look and sound.

1
Replace the stock air-cleaner with an aftermarket high-flow unit. This will allow air to enter the carburetor with less resistance, thus increasing horsepower. Additionally, since the engine will not have to work as hard to take in air, fuel efficiency will slightly improve.
-
2
Install a high-flow carburetor kit on your Monte Carlo. When used in conjunction with a performance air-breather, a high-flow carburetor maximizes airflow into the engine, and thus further increases horsepower and fuel efficiency. Additionally, throttle response will improve.

3
Replace the stock exhaust headers with aftermarket units that feature larger-diameter piping. This reduces exhaust back pressure, and thus allows the Monte Carlo's V-8 to breathe easier. With high-flow headers, both horsepower and fuel efficiency will increase.
-
4
Replace the stock cat-back exhaust system with a high-flow aftermarket system. Used in conjunction with high-flow headers, an aftermarket cat-back system will further free up the exhaust flow. For maximum performance, install a dual exhaust that features a separate piping system connected to each header.
-
5
Replace the stock crank and accessory pulleys with an underdrive pulley kit. Underdrive pulleys feature a larger diameter compared to the stock units. This reduces the power required to drive the serpentine belt system, and thus frees up horsepower that the engine can use for acceleration. Many underdrive pulley kits feature lightweight aluminum construction for reduced weight and maximum performance.
