How do you set the timing on a ls2?

To set the timing on an LS2 engine, you typically start by ensuring the engine is at top dead center (TDC) on the compression stroke for cylinder one. Use a timing light to check the current timing by pointing it at the timing marks on the harmonic balancer and the timing tab. Adjust the timing by loosening the distributor clamp and rotating the distributor until the desired timing is achieved, then tighten the clamp. Finally, recheck the timing to ensure it’s correctly set after securing the distributor.
