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

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.

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.
