It does not have one. The timing is controlled by the computer. You must have a OBDII engine scanner to adjust the timing. If you did not have the distributor out are move it then there is no reason to adjust the timing. It is done automatically by the computer.
The timing is computer controlled and there is NO need to fool with the timing as long as you have not moved or touched the distributor. It requires an OBDII engine scanner to adjust the timing.
That requires an OBDII engine scanner to do that. The ignition timing is controlled by the computor. If you have not moved are removed the distributor then there's no reason to fool with the timing.
how do you adjust the timing on a 1977 350 Chevy engine k-10
It should be 6 degrees before tdc, just make sure you disconnect the distributor's computer control wiring harness before you adjust, and check the timing with a timing gun.
you turn the distributor and use a timing light
You can not use a timing light to set the timing on that year engine. The ignition timing is COMPUTER CONTROLLED. If you have not fooled with the distributor then there is no reason to adjust it. But if you have bother it then you will need an oBDII engine scanner to put the timing back to factory specs.
No need to if the distributor was not moved.
it is preset at manufacturing !!
same as a 350
turn the distributor
