According to wiki

"195 in³ (3.2 L) straight-4, marketed as the "Trophy 4," derived from the right cylinder bank of Pontiac's 389 in³ V8, the standard powerplant Pontiac used in its larger cars, such as the Bonneville and Catalina. The engine was advertised as a gas-saving economy motor for thrifty consumers, but Pontiac also saved money because it could run the engine down the same assembly line as the 389. There were three versions of the engine: an 8.6:1, low compression, single-barrel carburetor; a 10.25:1 high-compression with single barrel; and a high-compression engine with a four-barrel carburetor. While the single-barrel version produced between 110-140 horsepower, the four-barrel was capable of 155 hp (82 kW) (SAE gross) at 4800 rpm and 215 ft·lbf (292 N·m) of torque at 2800 rpm. All three versions had a fuel economy ranging from 18-22 mpg, and the engine was generally reliable though it had a reputation as the "Hay Baler," a derogatory label applied by dealer mechanics (ostensibly from farm states) who experienced the violent kicks it could produce when out of tune."

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
