What are the degrees oftiming ignition for the L83 engine in 1982? I have, however, small changes. I threw injection and I put the carburetor. - Edelbrock carburetor # 1406 - Edelbrock Performer manifold RPM # 2101 - Edelbrock Performer camshaft Plus # 2102 - HEI ignition engine (high energy ignition) with Accel Super Coil coil 140003
Vette 1982 Collector Edition
With the exception of an 85 in tank fuel pump and a heated O2 sensor, my 82 is stock.
When I got Baby the timing was set to above the max to 12 degrees. I changed it back to the stock value of 6 degrees and have been using regular unleaded ever since.
The engine runs just a bit warmer and the performance is just fine for a daily driver.
Did you install a new ignition? The stock firing signal originates with the computer that fires the HEI spark module in the distributor. It the computer is still installed and operating it will be in the limp home mode. Mostly that affects the injectors and air fuel mix which you don't have. I don't know if that will change the spark trigger pulse.
Good luck and all the best from Tucson,
Nobody ever waves when I'm driving the Explorer.

I was thinking the same thing. Is the computer still in the car or did they change that also. If they did then I would guess you would be close to being a 1981 as far as timing and operation goes.
But I'm not that smart on it. I do believe that whoever is smart on this subject will need to know if the computer is connected or not.

Do you still have the original distributor? Does it have the two separate plugs? If it still has the separate, flat, 4 wire plug, you need to disconnect that, or change the distributor to an earlier model. Otherwise, you will not be able to have any control over the advance. If you have changed the distributor already, and it has a vacuum advance, you would typically want to see around 28* total advance for that engine, and compression ratio. There really is no one specific set-up that works for every engine, so you will need to "play" with it some to get the optimum combination.
