Cant decide what brand of opti's to go with on my new motor. I've narrowed my choices down to a GM opti or the accel opti. The MSD opti's are on crazy backorder and the Dynaspark is way expensive. what do you guys think?

IMO stay away from anything accel, except the dfi, i have never had luck with anyting they make. Also somthing seems odd that theres is only 200 bucks when msd's is 500-600.

 

Another question, Is there a difference between the GMPP opti and the OEM opti such as an ACdelco unit?

 

I spilled antifreeze on my Opti over the weekend, and now am facing the same problem. I removed my GM Opti this PM and it does not have any manufactures name or numbers on it. AC DELCO used to make all the electrical parts for GM. I probally go for the AC Delco since it is available for my 93Z for $488.00. There are rebuilts available from A-1 and Candone for $170.00 plus $50.00 deposit on the core. I do not know how good the "rebuilts" are. I hope someone responds to that question and soon!

 

Go to one of these two people for your a GM opti, about $260 for a non vented.
