Spark Plug

Hi, no additives Jasper engine with about 1500 miles on it. Started running rough so I decided to check the plugs. It is a 87 el camino with a 305 (Calif special) stock ingnition, stock carb.

Oh, sorry gap is 35

I will try that. Looking at the engine with all that smog equip seems you need to be a contortionist to get at these plugs. And small hands wouldn't hurt. 😂

Did some research , your right ! .045 is the way to go. Thanks
