Can you swap a 3.4 motor with a 3.8 in 2001 Chevy Impala?

Swapping a 3.4-liter motor with a 3.8-liter motor in a 2001 Chevy Impala is possible, but it requires significant modifications. The 3.8-liter engine has different mounting points and may also necessitate changes to the transmission, wiring harness, and ECU. Additionally, ensure that all components, like the exhaust and cooling system, are compatible with the new engine. It’s advisable to consult with a professional mechanic for a proper assessment and guidance on the swap.
