I have a 1994 GMC 1500 Sierra with 350 engine 5.7 what should the timing be set at?

The timing (base), is 0 degrees before tdc. Keep in mind the timing connector must be unplugged. usually a brown wire with a black tracer, has a single connector, located under glove box, or by distributor. Thanks...

Changing engines in a Chevy van 1986 not getting fuel and we have one plug i can find ware it goes its a two wire plug pink wire with black stripe and a gray wire and one other question some one told...

Is this carbureted or Fuel injected? What size engine? The plug sounds like it goes to the secondary air injection solenoid. If the coil isn't on top of the cap the timing adjust wire is tan with a black tracer and it is taped to the harness near the distributor.

How do you set the timing on a 350 chevy engine in a 1995 G20 van?

If the distributor hasn't been taken out, the timing can be set manually but you have to disconnect the distributor wire behind the glove box inside the cab. Tan wire with white tracer it is taped up to the a multi wire harness but is the only one with a single plug. Disconect the plug and use your timing light on the timing mark to set timing per specs. Rotate the distributor as needed to advance or retartd as required for the correct setting. tighten the dizzy clamp and plug the tan wire back together. The computer will now be fooled asd to what the base timing is and advance from there.
Contrary to popular belief, 96' and up do not have this wire. Timing has to be done with a programmable scanner.
Hope this helps.
