I just thought of this today, not that my car is running bad or anything, but since I have a 350 now, is the spark plug gap different between the Lb9 and L98? I mean if the L98 has different timing and fuel curves than the Lb9 then it should. Someone shoot me straight.

Thanks.

 

Spark plug gap is determined by cylinder pressure, plug operating temperature, electrode composition, and available energy of the ignition system. Advance curve has little if any effect on ideal gap.

In a word, "No."
