Re: L-78 Spark plug choice

NGKs are the ticket!!!!!! I had nothing but problems with the AC Delcos in my 396/375HP Motor, engine would miss at around 3,500 RPM.. The NGKs "woke up" the combustion chamber. Engine runs much better!!

I bought mine at the local parts store, Advance Auto Parts, and I think they were around a buck a piece.. Well worth it!!
