Important Considerations:
* This is a base timing. The actual timing will advance and retard based on engine speed, load, and other factors controlled by the computer (ECM). You cannot simply set the distributor to 36 BTDC and expect it to run correctly.
* You need a timing light. To properly set the timing, you'll need a timing light and access to the timing marks on the harmonic balancer (crankshaft pulley).
* Consult your vehicle's repair manual. The most accurate timing specification will be found in the factory service manual for your specific Suburban model. The year alone doesn't guarantee exact figures across all trim levels.
* Professional help is recommended. Unless you have experience working on engines, it's best to have a qualified mechanic perform the timing adjustment. Incorrect timing can cause serious engine damage.
In short, while 36 BTDC is a common starting point for this engine, it's crucial to consult your owner's manual or a professional for accurate and safe timing adjustment.
