coil choice?

[sdycke]

Hi ho. Anybody care to share about who makes good, correct igniton coils? Mine is totally stock. 1/6 seems to be acting up and might do them all (wires are getting replaced too).

[Kevin]

nothing wrong with the factory ones, are you sure it's not an injector issue?

[XfireZ51]

MSDs for 4 years.

[Paul Workman]

AC Delco last 4 years

[VetteMed]

AC Delco - last 2 years, 12K miles.

[GOLDCYLON]

[scottfab]

Accel 12yrs

Thanks for your suggestions! Once in a while this internet is good for something. besides poker. my bush league stress-test showed weak 1 and 6 sparks so....hello accel or d-e-l-c-Ohhhhhhhhhh. would anybody use a 'standard' coil....just asking!!!

For the cost savings of using a generic aftermarket replacement, it's really not worth the chance of it being of lesser quality. It's not like it's a quick job to swap out a bad coil, after all.

i'm still running the coils that came out of the factory

Not Accels!!

Not MSDs. I had MSD in my 73 454. They're crap.
Accels now working fine for 12yrs in the LT5.

I had an MSD 6a box on the 84 for 10 years.

I had the box on the 73 too. It worked great.
Coil didn't.

Funny you mentioned a mouse nest. First plenum pull revealed a terrific mouse....village? amusement park? definitely not just a nest. Had wierd dietary laws. Starter cable insulation and thats all. Asked about the standard cause I have one handy. but resisitance is 6 k ohms and originals are 5.3. Wonder if it would have made a difference. Oh well. will never know. Cheers!

When I did my injectors I replaced the coils with new AC Delcos,the coil for 1-6 died at 8000 miles.I pulled them all out and replaced them with MSDs.

Three years ago at Carlisle I had a slight miss only in 6th gear with a slight
load. When I got home I ohm check all the injectors and they were right on
specs. When I got to the coils I had a 5-8 coil dead. I got a new one from chevy but it didn't have the cyl numbers stamped on top but no big deal. Then
I thought if this coil went bad are the rest waiting till I put the plenum back on?
So then I thought if I change them all maybe I should put a better performance
coil so I went with the Accels.

They fit with a little bit of modification, you have to remove small plastic tabs
on each one so they sit next to each other again no big deal I used a hacksaw
blade only took a few seconds, took longer to find the hacksaw blade.:)

While I was doing the coils I decided to change those fancy ignition wires of
which I also ohmed and they were right on specs too but I replaced with a
new set from chevy without the logo printed on them. I cleaned and put the
original wires in the box for a later date.

I had about 28000 miles when the miss started and now I have almost 30000 and no problems but I didn't notice much of an improvement over the stock
coils, I just hope they last a long time. I'll see if I can post a few pics of the
coils, I'm just learning how to get pics up...jim

AC Delco is standard and they'll fire the 415's so they will be fine for yours.

[sdycke]

Thanks for all your input. In the end I tried 4 new MSD 8224's from Smut Racing and for my trouble got 8 misfiring plugs. A new Delco coil to replace the bad 1/6 and putting the other good, original ones back got 8 happy sparklers which never seem to miss a beat. Go figure. Is there a lesson here? You decide.

FWIW, on Monday I ordered 4 Delco D545 coils from Amazon for $34.27 each. It was the least expensive I could find online. I'm looking at Amazon this evening and they show the coils for $45.07. I was hoping I could point folks to a good deal. Anyway, if you need parts, it doesn't hurt to see what Amazon is asking when you're ready to buy.
