What is the spark plug gap for 350 Chevy?
Probably 0.35″ for a carbureted engine. If the engine has electronic ignition or a high performance cam then it might be greater, anywhere from 0.45 to 0.60″. I read one Chevrolet mechanic that gaps his plugs at 0.42″ in small block 350 engines. There is some benefit to widening the gap and he feels 0.42 is a “nice compromise.”
Why is there a gap in the spark plug?
Spark Plug Gap – understanding the basics. Large spark plug gap setting demands higher voltage (electrical pressure) for spark to jump the large distance gap. That means that there is higher voltage build up in the ignition system (ignition coil, distributor, ignition wires) prior to the spark discharge.
How big is the spark plug gap on a Promod Turbo?
Some applications such as ProMod turbo cars using M1 fuel frequently run a spark plug gap as small as .012″, even though they are equipped with some of the highest output ignition systems providing in excess of 60,000 Volts high current and high mJ power output.
How often should you change the spark plug gap?
The spark plug gap adjustment should not be changed more than 3 times and should not exceed .008″ in either direction. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage.
