timing is 6 degree before TDCAnswer
On my 1978 305 Camaro I've set the timing at 10 deg. before TDC. Sparg plugs used: Accel # 576 with .045 gap. I'm even thinking of increasing the timing to 11 or 12 deg. before TDC and decreasing the mechanical and vacuum advance a little. But since I don't have an adjustable timing light just yet, I can't tell how that would work out.
The timing degrees aloing with the proper spark plug gap, should be on the emission controls decal located under the hood in front of the radiator.
10 degrees btdc is good. but remove the vacuum hose from the vacuum advance first and plug it. set the idle at 750 rpm in drive if its an automatic. 550 if its a standard, then put the vacuum line back on. If you try to start it when its hot, and it bucks the starter, slow the timing down a bit, not much tho. the 10 degree will give you a little more pep. dont forget to gap the plugs at .046 . marlin
On the front of the timing chain cover, drivers side towards the top of the harmonic balancer.

There is no timing belt on a 305 unless it is an aftermarket belt drive system.

same as a 350

The easiest way is to look at the Harmonic Balancer. The 305 has a wider thicker balancer than the 350. Pus the timing tab on a 305 is located ON the timing cover and the 350 is bolted on the with the cover bolts. Riky9
Computer controlled and not adjustable
That requires an engine scanner.

The timing on that year engine is computer controlled. It requires an engine scanner to set the timing. YOU CAN NOT USE A TIMING LIGHT.
Chevy 302the 5.0 302 is a ford engine do you mean the 305?
on the left side of the 1979 chevy!
You could put a vacuum gage on the engine and time it for peak vacuum. A timing light is still better.
it is a knock sensor that is used to adjust the ignition timing.
It could be your off a tooth with your distributor

Just pull the camshaft gear of it should be just 3 bolts
Turn it clockwise to retard it. Counter clockwise to advance it. If this was not your question then asked it again.
