10* BTDC for all 1973-1979 manual trans trucks, except California
6* BTDC for all 1973-1979 California trucks, auto or manual trans
6* BTDC for all 1973-1979 auto trans trucks.
A 1976 Chevy did not have a points ignition, but that has nothing to do with the correct timing. You will find that the engine runs best with about 8-12 degrees BTDC.
If you mean ignition timing It is non adjustable The timing is controlled by the vehicles ECU best wishes
Dodge. Straight up.
the best ignition timing i have achieved using a dyno is 8 deg btdc at 700 rpm, using after market engine management
6, to 8 degrees advanced, or BTDC., will work best.

im guessing your problem is that the ignition timing is not adjustable. you'll need to align your base timing.(timing belt/chain)
That depends on what kind of timing you are wondering about... In a basic ignition there are two types of engine timing, static and dynamic. Static timing is the timing your engine runs at idle and low rpm. Dynamic timing is the variable (thus called dynamic) timing your engine runs on from low to full rpm. The static timing should always be set first, it depends on what ignition your motorcycle has...points? magnetic pickup? crank fired? there are several types The dynamic timing refers to the timing advance the distributor modulates through engine rpm. Setting this requires a timing light and timing marks on the harmonic balancer and engine block (usually stamped into the parts themselves from the factory). To help you out further I need to know what kind of ignition you have...a service manual will tell you what kind you have, and even how to adjust it. Best of luck!
poor or watered down gas or wrong ignition timing would be best place to start
There are contributing factors, however, about 6 degrees advanced or BTDC., should work best.
personally I would use an iriduim plug.
The difference between increasing the horsepower by advancing the timing, and advancing the timing to where it causes severe pre-ignition and engine damage is so slight it isn't worth considering. As an "increasing horsepower" idea, it is best left at the starting gate.
