Default New Optispark

New Chevy Buick Pontiac Ignition Distributor Optispark Opti Spark LT1 5 7L V8 | eBay


This link above shows a remaned opti spark with what seems like a too good to be true price IMO after seeing some rather high prices... The part number given is an AC delco unit.. My question is (because I honestly know really nothing about the lt1 optispark other than vented and non vented lol) does this look like a complete assembly? In other words, would I be able to take this and do a complete swap with mine (Plug and play)? It looks like he's sold quite a few of these with generally good feedback. But before I pull the trigger I'd like to know if there's anything else I should be looking for..

A few day's ago my car started running rough after being warmed up, it will go away after a few seconds but it seems inevitable that my opti is going bad.. I had a radiator hose blow right above it about a month ago and I have been waiting for a problem to arise, because it blew fluid all over the opti.. I'm going to check my ICM here in a few minutes but found this on ebay and saw a good price so I would like to know ASAP if it's worth buying.. Sorry about the long post. Thanks guys..

That might look like a "new" unit, but it does not look like OEM (GM, AC-Delco or Delphi). I'd say too good to be true, as you suspect. Buy at your own risk.

see and when I type in the manufacurers number it comes up as a ac delco unit. This is the Manufacture number given.. 1104032.. but Like I said I'm not sure what a GM unit looks like and if you say it doesn't look like one than I believe you.

GM units cost around $400, there's no way anyone can sell the genuine article for $52. Unless it's an eccentric billionaire running the company who wants to lose $350 for every unit he sells. You can't even buy a GM cap and rotor for that price.

I know the number they post is for the original GM part, but that does not mean that is what it is-only that they claim it the same thing. Think real hard and you will come to the conclusion that this has to be a cheaply made replacement.

Default Summit racing.

Last time i shopped for an AC Delco Opti Summit Racing had the best price. The AC Delco label was hard to find on the box at first but it really was an AC Delco unit. My last off-brand opti lasted <2 yrs (i think it was a Cardone unit but no longer certian). Make shure u order the late model ('96) Opti with the vacuum vent system (the first model Opti's had only holes venting to the bottom/atmoshpere).
Ok so i take a look at Summit Racing and see they want 450 bucks for an AC Delco now. Whew! I thought mine was like $250ish.

Good luck, sorry for the bad news,
cardo
