To identify the motor in a 1968 Firebird, start by checking the engine block for the VIN (Vehicle Identification Number) stamp, which can usually be found on the front of the block near the timing cover. Additionally, inspect the engine code, typically located on the engine's front passenger side, which can provide information about the engine type and production year. You can also look for any factory markings or decals that may indicate the engine's specifications. Cross-referencing the VIN and engine code with Pontiac production guides can help confirm the original engine installed in the vehicle.
The 77 has better metallurgy. Any advantages of the 68 318 are not specific to the block.
