Timing is controlled by the computer, adjustment is not possible.
Ignition timing or valve timing?

you dont, cause this motor does not exist from factory in 1998 expedition. only sohc
have the valves been lapped in properly,do a compression check,make sure valve timing is correctly set.
left one is exhaust and right one intake, set to the cam timing marks, do not forget the crankshaft timing marks too, there are 2 of them also.
There wasn't an option for a 4.3 in the 1993 cutlass supreme. You had the 3.1 and the 3.4 dohc as your options.
loosen the distributor, have a timing light, preferably an adjustable one, and it should be 15 degrees +/- 2 before tdc. ***See what engine code you have. If it is a Maxima SE (DOHC)(VE30DE engine code) you will have a timing chain instead of belt and probably no distributor. The GXE (SOHC) has the VG30 engine which has the belt...
timing cannot be altered. It is done by the PCM I think he/she meant the timing marks for the chain. No car today can have the time adjusted mechanically. You need a book for that. Go to the library if you don't find it here. in the internet
what timing are you trying to set? the cam timing or the ignition timing?
