You MUST have a engine scanner to set the timing. The timing on that engine is computer controlled.
That requires an engine scanner to set the timing.
The timing on that year engine is computer controlled. It requires an engine scanner to set the timing. YOU CAN NOT USE A TIMING LIGHT.
You will have to have an oBDII engine scanner and then go into the timing mode with scanner. You will then move the distributor by hand while watching scanner until it is in the specs. You can not use a timing light. The timing is controlled by the computer.If you did not have the distributor out of the engine are move it, Then there is no reason to set the timing. The computer will do it for you.
That requires an OBD2 engine scanner to set the timing. You can NO longer use a timing light.
That requires an OBDII engine scanner to set the timing to factory specs.
There is no more timing marks for a 98 vortec you have to go off marks on distribitor & use a scanner. You are setting cam timing
There is no way to tell you, because the timing is controled by the computor. You can not use a timing light. It requires an OBD2 engine scanner to set the timing to specs.
4 to 6 degrees advanced, or BTDC. NEW ANSWER: You cannot use a timing light on that year engine, It requires an engine scanner to set the timing. The timing is computer controlled. The scanner will allow your to set the crankshaft and cam shaft correlation and then the computer will take it from there. The above answer is correct for the early modal 5.7L 350.
5.7L 350 Vortec engine.
That requires an OBDII engine scanner to set the timing on that year. A timing light is no longer used, It's a thing of the pass. It is all computer controlled now.
line the timing mark from the crankshaft sprocket up with the camshaft sprocket and tada!
