MSD Optispark?
My optispark has gone out again. I have 31,000 miles on the car. The first optispark died of natural causes. The second was cracked "THANKS TO SPEED INCORPORATED IN IL". Now the third one has died. Has anyone tried MSD's #8381. I am looking for something better than GM. I appreciate any help or any suggestions. Thanks Jim.

Re: MSD Optispark?
If I recall correctly if you go with MSD you have you change everything over to msd... Me personally, I would just stick with OEM Acdelco

Re: MSD Optispark?
I have heard great things about the Dynaspark. A little pricey, but have not heard of any of them going out. Most guys do not want to spend the money on this when they can convert to a 24x system for not much more.
I have a Dynaspark on my car now. Was on the engine when I did my swap.

Re: MSD Optispark?
I called MSD today they said I would not have to change any other parts, but they do recommend a new coil and wires. I just don't have very much faith in delco optisparks. This is the 3rd one that has failed. The second one was cracked and then super glued together by Speed INC, so I guess I can't say that it just failed. Speed INC said that there was no way that the crack made the part fail. Guy was an A**. I never been back.
New optisparks from GM are remanufactured not new who knows who is rebuilding them. I have a friend who is a GM mechanic and he "thinks" that the remanufactured GM looks alot like A1 cardone, but does not know for sure. Another option would be Delphi cz20009 which are new and not remanufactured, but the cheapest I can find one is Ebay at $395.00. MSD is $431.00 on amazon. I think I am leaning towards MSD so far.

Re: MSD Optispark?
I remember paying $120ish for an opti back in 1998 for my 93 hawk. at the time delco was the only option.
the quality was hit or miss back then too.

You can always convert to coil packs.

Re: MSD Optispark?
one would have to actually drive the car to make swapping over to coil packs worth it.. that's just my me though.

I ordered the MSD and a new GM water pump last night. We will see how it goes.

Re: MSD Optispark?
Update. The MSD optispark has been installed with a new water pump and thermostat, also new belt. The install of the MSD went fine. The Firehawk is alive and runs great. The MSD also makes a "non-vented optispark" vented. Now my car has a spline drive vented optispark. The vent kit is included in the optispark kit and comes with everything needed. Nothing else need to be changed or purchased for MSD. Timing is also adjustable + or - 6 degrees if it is needed. Now lets see if it last longer than OEM.
