Getting ready to start up my 383.
Watched the HP show that spoke of E3's. Just wondering what you are running.

Due to my heads a needed a long reach plug and due to my headers I needed a short "header" style plug.... sooo...I run an AR132 Autolite

I run Accel "shortie" plugs...never had any issues...

Autolites work great for me..ac's in my stock driver!!

,I run Autolites,..have for 30 years. You can spend much more but, why?

I use accel shorties in my 327 due to the headers. No E3's out for it yet.

I just put the E3's in my dad's F150 (80,000 mi) less than a tank ago so we'll see how those do. He says the acceleration is much smoother.

I'm running accel shorties on my 355ci with headers. No problems.

autolites. #85, if i remember correctly. one or two are a pain with headers, the rest are no problem. might try some shorties one of these days.

Autolites in everything not under warranty.

Autolite 24s

I'm also running Autolites, #303, in my 67 high compression 327 motor!

Autolite AC13 or AC131 can't remember which.

I like NGKs. If you try any fine-wire plug, be very careful not to stress the center electrode if you need to adjust the gap. I don't see the E3 plugs working any better than the Bosch multi-electrode plugs.

ngk works good for toyota's..i agree with you!!...the problem with ngk is they come pregapped for cars, its hard to change the gap with out ruining the electrodes!!

I use NGK's and don't have any problem changing the gap.

Autolite 3911s work great for me.

ac delco R54ts here..
