99 Suburban Timing

#1

I have been told that pre 96 model 5.7L, you had to disconnect a wire that
went to the computer to time it. Would this be the same on the 5.7 Vortec?
Is there a trick to it?

#2

I believe you will find the is fully computer controlled timing. Look at the
emissions label under the hood.

Correct.

On a 99 (as in the subject line), no.
The timing is totally based upon the signal from the crankshaft
position sensor, the crankshaft position sensor is in a fixed
position and short of major machine work, is not movable or
adjustable.

The trick is; you can't do it.
