    Timing seems to be off on the 350 TBI in my '94 Silverado.

    What should the initial setting be (0 degrees), with the Computer wire disconnected?

    There should be a placard under the hood somewhere...

    Start engine and bring to normal operating temp. Unplug the base timing connector located in the distributor wiring harness tan wire with a black stripe use a timing light and set timing to 0 degrees at idle. The timing marks are on the crankshaft pulley and a tab on the timing cover with numerical indications... I think this is what you are looking for...
