This is a clarification of why I say I saw a difference.
30 yr old truck with a big pig engine -vs- small more modern design V6
I don't have the paperwork any more, but we have been under emissions testing here since 1996 and was provided with the test results, actually HAD to have the test results to get license plates.(still do). I had a 1997 Buick Skylark with a V6 that ran very nice. According to the sniff test, the truck ran cleaner than the car. The test encompassed putting the vehicle on a dyno type of device so they could test at varying speeds. A 454 with a rudimentary fuel injection ran cleaner than the V6 Buick did AFTER I put the box in. We are on odd and even years, so a 91 and a 97 had to be checked at the same time so I could get my plates on my birthday, that is how Ohio does it.
We are not as bad off as California is though.
Of course, OBDII is a snap, just plug it in, passes or don't and away you go.
A couple miles a gallon was very noticeable.
Did it make x more HP ? Can't say. Did it run better, absolutely. It was burning up more of the fuel, especially the unburnt hydrocarbons. The 454 of 1991 was not as efficient as the 454 of a couple years later. Simply by unplugging the box from its power source changed the feeling of the engine. As I said, the "crispness". It didn't turn it into a race truck, not saying that.
It did get better mileage than the 1989 454 that ran off with my ex-wife. (same gear ratios, both were 4x4 with 3.73:1 differentials) I still had/kept the horses though, kept the place, she went down the road. When you are hauling 10,000 lbs of horses and horse trailer behind you, you can tell if something has helped or not. I pulled the horses all over and hauled lots of hay with that truck, both for myself and others.
This is what we have been living under since 1996 and what I judged by. Very scientific.

as far as my experience cleaning up exhaust, on the 67 it made no difference other than my vacuum advance doesn't play as well... so mileage actually dropped in that instance. I always wondered if it had enough spark energy to jump out early when commanded by the ICM... and that caused the issues I had. It would buck like it were over advanced.

I guess EVERY FORD in like the past FOREVER is defective then, because they hit multiple times at idle. ALL of them.
In STOCK trim too.
Your turning into a real troll with that post. COP has SO many advantages it isn't funny.

frankly im tired of explaining why a $69 optispark doesnt work well. Or even a $500 MSD optispark doesnt work well either.
Or explaining how a vent kit fixes problems with the 92-94 design
people wanna re-invent the wheel, have at it

How else is it explained to the daily newbs that join with questions on it or the misconception that ‘the optispark just sucks under all circumstances’ bc either they (or the PO) put in a cheap optispark that doesnt work.

II think it's bothersome b/c it's misinformation. At LEAST bordering on it. Diz repeatedly states that Opti's are better than anything that's come since....that ain't true. He starts threads asking if anyone could or has adopted Opti to and LS engine. It's absurd and at best, a waste of postings. At worst, the unwitting might be confused by it.
I like Diz...but the opti thing is ridiculous. I "get it", w/his perspective that opti's also aren't the worst thing ever/total junk/fill-in-the-blank with what people say about opti's. I feel that they're (good ones) are pretty darn reliable -at least as good as GM said they would be, and they're definitely not that hard to change if they do have a problem. Worth changing them out? I'm with Diz, here and say "no", not worth spending $1200+ to change to something else, which is why I still have an opti. BUT others feel differently, so I posted when I saw this MSD system...just one more option for folks.

My point totally. Misinformation does nothing for anyone. Differences of opinion are one thing but to ignore technology and dig your heels in because "you stand by what you say" is ludicrous. Optis are what they were for the time. If not for better technology, then why did they abandon it? Diz claims to be an engineer. His entire profession is built around advanced technology. Should we still be using adobe to build our houses? **** and tube wiring? Maybe hall in some wood for the furnace. As mentioned, to post if the opti is adaptable to the LS series just begs for comments such as mine - or, "What has to be done for the C4 to beat the C8? That's like asking what has to be done to a Spitfire to out-dogfight an F18!

If you don't mind me asking what is the LT1 distributor hole mod? We are talking about OPTI spark delete right? I really really would like to get my car running by summer but I refuse to waste any more money by putting another opti spark in my 1992 corvette.I have put in the vented one like on the 1994-96 models and that has gotten me oh about 4 month / 800 miles. That was last year, the car currently has 78,000 mile on it. Torq Head support told me that they don't make a kit to fit the 1992 & 1993 corvette for LS conversion because of the OEM wiring on the corvette is vastly different in the 92-93 & 94-96 corvettes in addition Torq Head said it didn't plan on making one. So if anyone can help point me in the direction of somebody that sell a reliable opti-spark deletion kit for a 1992 & 1993 LT1 I would for be ever grateful.
