Going with stock 95-97 GM unit.
Going to get the MSD repaired and sell it. Seems it is not very good unless MSD fixed the problems which I doubt unless others can vouch for it on here. I was on the fence when it came to the Dynaspark unit. Looks really nice and will run the factory unit for the next couple years and see what happens. Hope boost has no effect on it. What BENEFIT will the DYNASPARK have on my car. I already have an MSD coil and running a FAST XFI stand alone computer for the turbo 383 motor. All I can see is it may last longer...then again some people are syaing some of the OPTIS can last 50K and others last 200K. I would be happy with 50K...hehe!

my experience with my msd is good for the most part.after about 9000 miles it started to give me problems.backfire,cutting out,missing.so i pull it off and find that there is some play in the big bearing.probally my fault since i had a hard time getting it to seat all the way into the cam and used the bolts to pull it the rest of the way in.stupid on my part.when i got it back from msd it had a different brand bearing in it and the invoice referred to it as "heavy duty blue bearing" and it works great now.if your opti is vented make sure that boost isnt being blow into the opti through the vent line.

I think their internals are good, as they make great parts otherwise. I think it is there Opti Sensor. I hear you can by them, made in USA, but generic. Now, GMs use Mitsubishi, and meet OEM requirements....

this is probally not the greatest thing in the world to do but i have 3.73 and i basically use the rev limiter to control rpms while i drift or when doing burnouts.what im getting at is i dont think going up against the rev limiter is any thing to worry about.

Not a lot of help, but for those of you who want to get rid of the optispark completely: http://www.eficonnection.com/eficonnection/default.aspx
My buddy was one of the original testers of this system and has 0 problems and drives the installed vehicle all the time.

Another issue for people that replace there cam at the same time as ther Opti is you must make sure yout cam pin is within spec. I believe it's .620 long. Any more and it will cause premateure bearing failure. From what I was told all CompCams are made to fit the late gen. Opti's. So if you order one for a 92 LT-1 the pin and hole in the end will let you run the vented Opti's. Also I would reccomend from all the post I have read to open any brand up and check the bolts on the rotor.
I put 130K on my factory unit so I decided to stay with stock. I just bought a new A/C Delco on this board for $200.

I have owned my MSD for 2 years now. I sent mine back because I suspected it was causing a miss and back fire at start up. They changed the bearing and the sensor and shipped it back for a total charge of $64.00. The downside is this MSD has less than 5000 miles on it. BTW, the bearing did not seam to be bad and let me tell you I have seen plenty of bad bearings on the stock units. I guess they automatically replace the bearings no matter what. Good policy.
This unit is going on a new motor. I plan on adding a groove on the flywheel and a tab on the timing cover. Hope it holds up.
