Timing Setting

[ls1 nova]

Not PT but what is the timing set at on a 1994 full size blazer. 350 cu. And where is the plug you have to disconnect? It is not under the hood. Thanks for any help!

I had a full size 1991 Blazer, there was a brown wire with black stripe under the panel on the pass side of the engine, on the firewall.
The radiator support has a tag with the timing specs, sold the blazer so I don't recall the timing specs.

If it is not under the hood then it is a single brown wire, maybe with a black stripe, coming out of the harness under the glove box area. Unplug it, start the engine and set initial timing to 0 on the pointer, shut off engine, plug wire in and restart engine.

Should be under the hood behind the plastic cover on the passenger side firewall. Tan wire with a black stripe, disconnect start engine and set timing to 0 degrees.
