Would the plug gap be different from a 350 to a 383. What do you guy have your plug gaped at

 

depends on plug, compression, fuel and stuff i would think

 

The plug gaps would be the same for a 350-383.

How much cylinder pressure and spark energy you have would dictate plug gap. Also the type of plug used.

I run a conservative .035 with Autolite 104-103's and a Deltec. I might could go wider on the gap but it works well like it is.
