Wow!
It looks like the only two choices are the MSD and Dyna.
I can't comment on the quality of Accel products since I'm an MSD guy.

Good Information everyone

Default May want to wait on MSD

The optical portion on my gen 1 ('92) factory opti is not fully working. I bought a gen 1 MSD opti to replace it, but it arrived with a hole in the top of the case, where the Air inlet port was supposed to be. Called MSD and they confirmed that it was a mistake. I returned it. I figure if something that obvious got by QC, I just can't risk using the product, considering the labor to install it. Also, the machining of the aluminum case seemed crude.

Dynaspark has been backordered on gen 1's. Seems like they are a very small shop, so there may be some risk there, on future service & support.

Only other alternative is another non-vented factory opti, gulp, but at least that is covered 12mo/12k, if I have the local Chevy dealer install it. They have a great vette mechanic, he says he has not had one come back, and I see some forums that say the factory opti problems are overblown.

Not sure what to do, but need to do something soon, the vette is not fun when it hesitates intermitantly...

I just checked on summit and they want 499.98 for the MSD opti. And if thier opti is as bad as thier blaster 2 coil's or thier 6a boxes then they are probably junk.

Ive seen one that someone took apart to inspect. It looks pretty impressive granted we dont have many options anyway. I hope Accel and MSD do really well. We need them to do really well lol. I would love to see the insides of the Accel.

I never had much luck with MSD (May Strand Driver) products. I bought a MSD 6a box with a Blaster 2 coil for my impala SS which has a LT-1 in it and I installed it using thier harness so it was hooked up properly. I fried 4 coils and 2 boxes in a matter of a month of taking delivery. That is why I am leary of buying ANYTHING MSD ever again especially something that takes several hours to swap out when it breaks

Honda hunter was charged $307 for a rebuild because the inside of the distributor was saturated with oil, and there was actual dirt pieces inside the distributor. Everything needed to be replaced (except the housing.) I feel that it is necessary to explain the cost because I do not want our customers to assume that everyone pays that much for a rebuild. Not only are rebuilds extremely rare but they can also cost as little as $80. I just want you to be informed.

This is a lot more in line with what I'd thought was typical. Good to know. Thanks for the clarification.

Be well,

I'm not complaining. Just never expected to have to pay that much but I didnt have a problem paying it. At the moment options are limited and I dont want Delteq or LTCC so Ill stick with you guys until otherwise. Also my post wasnt ment as a flame to Dynaspark or you. I didnt see anything wrong with posting what I paid.

After reading what you posted I felt that some people may not interperate it the way you meant it to be interperated. This is why I chose to elaborate on it and shed some light on the situation. I just wanted to clarify so customers can feel better about the rebuild service.

The Gen III Opti is that the kit that gets rid of the opti spark ignition completely. If so how much and when can I get it and is it a simple bolt-on type application or do i have to take the motor apart to do this. Can I just upgrade to the Gen III Opti without buying any other Gen II optis or anything. I am asking this because I was told by my mechanic that my opti doesnt have too much longer and I was thinking about getting rid of it if i can.

Its hard for me to tell what you're really asking here. The Gen III is a rotorless distributor that can only be used with a coil conversion system, ie: delteq or ltcc.

Is it as easy to install like a traditional bolt on or does it require major mods. and it totaly phases out the opti even the optical trigger. and how much or are the prices set yet.

Buy the vacuum line kit and install it before you install a GM non vented one. I went thru two on my wife's 94 L1 TA before I installed the vacuum kit and used Hi-Temp sealer on the gasket and where I drilled the hole for the vacuum line. So far she has gone 60,000 miles with it and a new water pump. One bad plug wire will kill a GM unit too so take care and check everything.I too am waiting for a better option as my 96 LT4 has 72,000 miles on the orginal opti spark and water pump,so iknow it is a matter of time before I am calling a wrecker.

I went with the Dynaspark Gen 1. Apparently no longer red, mine is black, with a factory looking mustard cap cover. I was surprised to see the external RTV around the case. I thought the case itself was designed to be liquid proof, but maybe that is just extra protection. Had local vette mechanic install it. Also new wires, plugs, and a couple of seals on timing cover. Running well. Only issue is a couple of times, during rolling stops, when restarting in second gear, I got some hesistation at low RPM's. I can't recreate it though. Not sure what might cause that. No general hesitation issues after warmup, like I had with the old one, so big improvement.
