i need to know what the timing specs are for a 87 grand national and how do i adjust the timing, thanks

Timing is adjusted by the cars computer. You can adjust it through some chips like a Turbo Tweak. What are you trying to do?

Correct.

Timing control is done by the program in the chip inside the computer. And will vary from chip maker to chip maker.

As is engine idle speed, coolant fan, tq converter lockup, egr, boost control, etc etc etc. Its all done by the chip.

Only adjustment you can do is throttle position, throttle blade opening, and cam sensor sync. Fuel pressure IF you have an adjustable regulator.
