We would take a matchbook cover, and fold it in half, and use to gap points on my old chevy, lol, poor kids we were.
That's right, I forgot that trick, worked well. Thanks for that memory!
The things You/I remember. Wonder if that is senility creeping in???
I do not have that luxury of blind faith. Being a professional Technician with advanced diagnostic ability, I've observed how careless delivery/handling personnel can be with automotive parts. In all but rare circumstances, my double check of plug gaps show that nearly all of them are out of specs. Does a mere 3 thousandths of an inch variation matter? Yup! But that would be imperceptible to the naked eye. I can see that difference on a secondary pattern on a good oscilloscope. Inasmuch as EEC (Electronic Engine Control) management over the entire driveline for optimum emissions "Lambda" (perfect 1.0 stoichiometric) is so critical, the spark plug gap is where the entire process originates. Everything else is designed to follow that. Any deviation from specified plug gap changes KV demand in the coil. Fuel and engine mechanical issues can make a difference. But that plug gap is SUPER important. The late Mac VanDenbrink expounded upon this in training techs through the years.
SO has SAE and METRIC huh, hee hee.
How to Gap Iridium spark plugs
In this video we dive into how to properly gap Iridium spark plugs and go over a few tools to do the job. Gapping these plugs is often done incorrectly leadi...www.youtube.com
I still have one of these from my Dad,it has to be at least 55 years old

We used to spray water into the carb on a hot engine while it was running to clean out combustion chambers,lol
Don't care what the factory or dealership does. I check every plug, every time, prior to installing. I've seen enough plugs that were supposedly "gapped to spec", indeed, not gapped correctly at all. Just my personal preference.
When I was at Cadillac in the 70's, I rebuilt a 472 engine. I had to replace one piston. Those engines used alphabet letter ID's for specific pistons "A"
Ignition coils failure is 99% due to a spark plug issue. That comes from training and experience. This means that if you have a bad coil, and do not replace the culprit spark plug(s), you will have a repeat problem.
I'm painfully aware of that one too.
when Chevrolet redesigned the Lumina for the 1995 Year model, they redesigned the HVAC air handler under dash too. The newer one was easy peasy to replace in comparison.
Yeah dat 199o was a freaking bear.
Used to be lots of the little Monza Spyders up here,but the majority of them had the little Buick 3.8 in them,although there was the odd smallblock one,but as far as i know they were 305's,as i thought they only put a 350 in the Monza in 75,and the Spyder wasn't available until 76,and after 75 they were 305's.But i've been wrong before.

Personally I just use feeler gauges, never had an issue. But then I'm careful and take my time with them.
I SAW and drove a Monza Spyder. As to the particular year model, I do not clearly recall. This was in early 1983Used to be lots of the little Monza Spyders up here,but the majority of them had the little Buick 3.8 in them,although there was the odd smallblock one,but as far as i know they were 305's,as i thought they only put a 350 in the Monza in 75,and the Spyder wasn't available until 76,and after 75 they were 305's.But i've been wrong before.
This one was at the local show yesterday,but it was rough.
The local GM dealer had one of the rare smallblock powered 77 Mirages,it sat in their showroom for almost a year before it finally sold.
Let's check out the 1977 Monza Mirage!
There were FOUR 1977 Chevrolet Monza Mirages onsite at this year's GM (Chevrolet) Nationals June 23-25, 2017.
My cousin owned one,it was a 79 Spyder with the little 3.8 Buick,it was actually a spunky little car,it was white with the decals and striping done in red so it was even a good looking little car.
One of my old running buddies had a 454 in a Monza just like the one in your photo. His was silver.... and it was stupid fast. Also lit up the night sky when he popped wheelies at night. It got terrible gas mileage, but he didn't care.
That would of been a handful on the street,lol. Go like hell in a straightline,going around corners or stopping it be dammed
He had beefed up brakes, subframe, traction bars, 9" Ford diff. It handled and stopped fine. I rode in it once with him.... Only once.That would of been a handful on the street,lol. Go like hell in a straightline,going around corners or stopping it be dammed
