Take a known good spark plug and connect it to one of the spark plug wires. Ground the plug to the block and watch the gap for spark while someone tries to start the engine.
Unless your radiator support decal says different, it is .045
1,8,4,3,6,5,7,2 same as the firing order
the gap for the 1983 Chevy c10 silverado is 0.035 ("35 mils") 0.889mm
The firing order for a 1994 Chevy 1500 Silverado 305 from the distributor cap to the spark plug is 1-8-4-3-6-5-7-2. To locate the number one plug, look for where the wires plug into the small square on the driver's side, two pegs clockwise from that square is the #1 spark plug.
