just a fast ? is the msd coil worth it the 45.oo bucks ?

I've got the MSD coil, it made zero difference in how the car runs.

I'm only running a stock engine with bolt-ons though-- I'd imagine on a really built engine it'd make a bigger difference.

My 2 stock style coils leaked the ign discharge.. At night you could see it sparking/arcing on itself... Not the MSD unit though

I've got it and no difference really...it is red though.

The early LT1's had a weaker coil than later models, but I'm not sure to which years that applies. You might get a little hotter spark on an early model LT1. On later models, it might be best to just use a stock replacement.

By the time these car were made OEMs really stepped up their game ignition wise to meet idle emissions requirements and they were stretching the tuneup intervals. You will find most knowledgeable folks around here will say ignition "upgrades" are a complete and total waste till you are looking at something like boost or juice.
I have tried a couple ignition boxes on my car over the years, one caused nothing but trouble and the other made something between no difference and a .05 slower at the track. Now granted the 96 coil was slightly upgraded from the 95 and earlier because they went to a full 100K tuneup interval but still the 95 and earlier are quite good.

I swapped one in when I had a bad tune on the 383 and it made a little difference. Stopped miss firing as much as it was at higher rpms but then again the stock coil had a 94k on it and I got a deal on the MSD coil and spare ICM with heat sink for like 35 bucks shipped from a member on here. Couldn't really tell you if it made a difference since the tune was what was bad. It ran pig rich and fouled out O2's and plugs. The coil was just to make sure it was the tune and not the coil or ICM going bad. I'd say no it wont make a difference. a Fresh new coil may though depending on how many miles are on it. It's still on the car and works fine.

Every stock component has a limit, but if you're not pushing those performance boundaries then save some money by buying the stock replacement (it's $20 at Pep Boys). This is especially true with FI and ignition parts. For the most part they either work or they don't with your application. The OEM stuff is pretty good.

If yours is working fine don't change it. My stock one was arching so I replaced it with the msd one and also spaced it out from the head and been working fine ever since

I needed to replace my 100k stock one because the coil wire terminal was eroded. I bought a BWD Select coil at the auto parts store. It's a nice unit with a brass terminal and it's made in the USA. No performance difference but then I didn't expect any.

If you do get one they just changed the casing of the coil but the part number is the same. Also be sure the coil says msd on it. Their off brand that the parts store carry are junk.

I had a popping at 5500 rpms and above. Thought the opti was about to go or the cap and rotor was carbon tracked. Changed to an MSD coil just because the original coil was 19 years old. Popping was cured and the light fuel smell coming from the exhaust at idle got noticablity better.

Ive had a lot of customer with LT engine who have had much better luck with the MSD coil over the stocker

Do you guys carry the stock coil?

Did you try an OEM unit first? You can't really compare a part that's 1-2 decades old to a new in box MSD.

Why would you want to compare then when you could just sell the aftermarket one instead?

Not worth a damn. I had an MSD that died on me going down the road. Did nothing for performance.
