Rebuilt the motor in my car about 4 months ago and installed a brand new summit brand opti in the car because the car still had the original. Well, the summit brand opti has since took a dump on me, what is a good replacement opti for the money i know GM wants 350 for theirs, any suggestions.

 

I am on Opti #6. I have used...
Summit - failed encoder.
GM parts - failed rotor/ failed optical encoder.
GM parts - fouled w/ fluid.
A after market from a vendor in Indiana - Corosion failed rotor. Not worth $600
All-ignition.com - now use w/ good success (note: many did not like them, but, this is their Hipo unit for $300) I like it. Looks like a clone of the MSD unit, and, good price. Yes, I ue a hg ergy Ign w/ 8202 coil FI app.
Hope this helps.

GM opti.

 

My factory one was still working fine at 110,000 miles but I replaced the water pump and put the MSD cap + rotor kit on. Has been fine for 20,000+ miles so far.
