2006 Chevrolet Impala
Power choices begin with two larger and more powerful V6 engines. The base 3.5-liter V6 churns out 211 horsepower and 214 pound-feet of torque. The 3.9-liter V6 generates 240 horsepower, a 40 horsepower gain, and 242 pound feet. Each six gets a “push-rod first,” variable valve timing, and are linked to a four-speed automatic transmission with available floor shifter and traction control.

under the hood it says it’s a 3.5
maybe a previous owner replaced the engine, or they stuck an LTZ badge on the car.
The Impala came with a 3.5, 3.6, 3.9, and 5.3.
Check your VIN number.
Check the sticker under the hood.
Check the engine itself.
And check the beauty cover.
see how everything lines up.
no 3.6 in 2006
GTK!!
Just checking out of curiosity and found an older impala forum thread regarding the same topic. One person stated that his Hayne’s manual states that the 3.5 has the serial number stamped on the left side rear of the engine block, while the 3.9 has the serial number stamped on both the front and left side of the engine block.
