unscrew the distrupittar cap and turn it till it's right, make sure you use a timing light, if you don't know what that is then please, do everyone a favor and have a professional do it. Actually, since you asked how to in the first place, have a professional do it and save yourself the potential the get hit with 80,000 volts, or getting you fingers chopped off from the fan.
how do you set timing on a 1985 350 gmc truck
You have to use a scanner.
0 degrees at TDC.
Mines a 5.7L and its 350. They have many versions of the 350 though
It sets in 0 degrees.
It is not adjustable, its controlled by the computor.
195 hp
YES, As long as the GMC 350 is a 1988 to a 1995 year then it will bolt right in and work just perfect.
To set the timing on a 1994 GMC Suburban you need to warm up the engine while the car is either in park or neutral. Next, you adjust the distributor until the timing is set to where you want it.
YOU can if you have an engine scanner. if you have not fooled with the distributor then there is no need to adjust the timing because it is controlled by the ECM / computer. It will adjust it's self.
helps to have the year but 96 and up are computer controlled and there is no timing adjusment only cam adjustment
there should be power pack coils and cam and crank sensors rather than a distibuter and timing is computer controlled the only way to adjust it would be by changing a chip.
