How do I figure out exactly what ls engine I have?

If it's stock and untouched, the numbers on the corners of the Heads narrow it down fast. If it's still in the original vehicle that's even better..

If you have the original factory Powertrain Control Module (PCM) that was mated and factory married to this motor, you can pull the Vehicle Identification Number and decode it to discover it precisely. HP Tuners or PCM Hammer can do this file pull from the PCM.

Gen 3 LS motors have the oil filler cap on the passenger side, front of the head, through the valve cover. The dipstick is midway down the passenger side of the motor. What year is your motor?

If you're looking at it in the car, front passenger side you'll see the cap on a filler neck in the Valve Cover.
