I need a new opti for my 95TA. I don't want the crap that Autozone sells. I need the complete unit, that GM sells. I *think* I've seen on here a dealership that sells them for $187, but I could be wrong. Let me know. Thanks!!

Jason Cromer, see thread above yours titled "Jason Cromer" has all the info in there.

 

anyone else? I'll be making some calls tomorrow. Thanks a lot!!

 

Dal or Jason Comer are good people..Last time I bought one it was 217 for a vented opti...not sure what Dals # is either..

Yo

What does the Opti do anyway? What happens when it goes bad?

 

Doh!

 

The optispark's basic function is to remove currency from your bank account..

Actually.. It's an optical based distributor that's located behind the waterpump (on the front of the LT1)..

It optically judges the engine speed and position to determin the spark timing and other things..

When it goes bad (which I believe mines doing right now) it can cause all sorts of problems.. Bad timing for one.. It can make the engine run rough or not run at all..

I want to go with a non-optispark alternative (coil pack system).. Problem is they are not as available as I'd like.. (Electromotive stopped making the SDI kit for LT1's)

The optispark is nice, but an unvented one (like mine) is just an expensive money pit part IMO..

 

Dynaspark has a nice opti, but it isnt cheap, I think its around 599 but they say its bulletproof, plus it looks cool!

 

i have a dybnaspark...cost me 667$$ with shipping...
well yea its badassssssssssssssssssssssssssssssssssssssssssssss ssssssssssssssssssssssss..................havemnt had n e problems with it...now time for me to install my hooker LT's, cam, lifters, srpings, pushrods, roller rockers, and maybe these ported heads....
