The recommended spark plug gap on a 1996 Chevy C1500 with a V8-305 engine is .060"


Sorry but I do not under stand your question.


Drivers side, first spark plug in front is #1


Depends on the year, but the 305 used the AC Delco R44t for years.


.045 inch , according to my Chilton book



.35 inch NEW ANSWER: Sorry but it's .060



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.


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.


spark plug gap about .45..............the hp is 185


Unless your radiator support decal says different, it is .045



the gap for the 1983 Chevy c10 silverado is 0.035 ("35 mils") 0.889mm


The #1 spark plug is the furthest forward on the driver's side. Follow that spark plug wire back to the cap and it would be the one you seek. Most of the time it's the tower closest to the #1 plug, but that's not as important as getting the firing order correct.


Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.


It depends on what heads and ignition system you're using. You'll have better luck with AC plugs in a Chevy.


It is important to gap the spark plugs at the right size. The spark plug gap for a 1981 305 Monte Carlo is .045 inches.


front driver-side near manifold and spark-plug single green wire



take out the # 1 spark plug turn the motor to top dead center remove the dist. cap and where ever the rotor is pointing is # 1


.35 , you can also check the label in the front of the engine compartment, it will have all your gaps and timing specs


There are 8 of them, 1 per cylinder.


This is a guess because of lack of year, engine size & model 305/350? 1,8,4,3,6,5,7,2 is the firing order in a clockwise direction. # 1 is driver side front plug its a Chevy v6, 4.3
