why didnt anyone mention dynaspark???

 

cuz he asked for the 2nd best.
1=gm-used
2=msd-used
3=dynaspark (maybe 4?)-seen one go bad with a friend, coulda been a fluke, still shy away from it

 

I think what he is asking is if you buy a new opti today, is it more improved than one bought new in 1997... I would guess it's the same thing.

 

my advance done good then i got a msd one.

 

GM replacement how can you go wrong? only after 100k more or less

 

The delco one is the best choice.
The dynaspark is the second best because it used a lot of stocker parts but it is too expensive.

Msd...no comment

Please stay away from Accel.They come with an oil lite bushing instead of a bearing

 

The only EBay vendor I've seen that sells an actual AC/Delco unit is thepartsladi and they're quite a bit more than 150. Maybe there are other vendors selling actual Delco units for 150, or perhaps there are a lot of vendors selling the same junk.
