Was that sparks at min 41 from the plug wires?

You now have a monte ss, and a grand national. I think its safe to say you've found the automotive G spot lol

Randy, I'm an old school GM tech. I can tell you that design of MAF was used on a lot of the GM SFI engines back in that day. The interesting thing was, the C3I distributorless ignition system was prone to popping back through the intake during cranking on occasion. It normally happened when you just didn't hold the key QUITE long enough for the engine to catch, and it would pop back through the intake. Trouble is, that particular MAF would get blown the hell apart nearly every time it did it. I replaced COUNTLESS MAF's on these, 88 Royales, 98 Regencys, Rivieras, Bonnevilles, you name it.......pretty much all the GM cars that had the early C3I system, with this design of MAF. Guaranteed, you have a bad MAF, and the intake pipe situation is trash - fix these two items, and that car will probably shock the hell out of you.

The horsepower numbers were underrated for insurance prices back then. Quit a bit above the factory numbers. If it has an aftermarket boost controller it most likely isn’t stock. From those that I’ve known who have/had Grand Nationals they don’t really like anything less than 93 octane. Those tires are meant to keep you from spinning in order to plant all the power on the ground so they are the better option. Guarantee when it’s running 100% right it will still spin them if you really want it to.

It is your car, your money. Do what you want with your car and ignore the negative, sad people.

Even with all of its faults, I still love that Grand National Randy! I think that one fix you mentioned using a LS1 maf sensor is the way to go. At least you can get replacements for them. I can't wait to see all the fixes on this one. Those replacement ties and wheels you put on don't look that bad for now. They will work. Running around on tires that scrape and rub all the time sucks. Ask me how I know. When those other 15x7's become available, you will get the G.N back to what it should look like. Great buy Man!

We do really want this Buick Grand National and the Monte Carlo SS be part of the power tour 2024 cause that would be so cool looking forward for it! Your fan from the Philippines!

Wow, you just brought back some great memories with that Grand National. How nostalgic!!! I love that car. I dont mind the new rims at all. To me they fit the Era of the 80s. I look forward to seeing more on this car. Love your videos always

Looks great. I had a 1987 Buick t-type metallic blue with the limited slip differential. It was a fast and nice car up until it was stolen and burned 7 years later.

love love love the GN and the SS just need another Marauder to complete the trio

Hey Randy, Alex @ Legit Street Cars bought a Grand National with the same engine issues and wheel and tire issues. He has several videos on what he did to fix it all. This might save you some time in diagnosing the problems. Nice car. Watch all your videos.

Congrats Randy 🚘👏👏🤘. My old man had a T type back in the day🎬👍.Salute 😎

Been Waiting on this one. My friend had a Buick T Type similar to the GN

Great find Randy and WOW it looks pretty damn clean as well as being all there! Seems like price wise you bought it mucho bueno. 😊

Love the videos Randy! This is a great looking Buick and I bet you will love it. Keep up the great stuff and can't wait for whatever you got next!👍👍

Great video Randy! looking forward to see what you are going to do with the Grand National.

I absolutely love the Grand Nationals. I follow all the Mecum and Barrett Jackson actions and I think you got a pretty decent deal. Great video and looking forward to seeing all the progress.

Wesssss ..that last test drive gave me chills omg reminds me of the days of YORR

I have a 2004 Buick Park Avenue Ultra Supercharged Series III and my engine did that and I had to get a New OEM fuel pump and Fuel Filter and use no ethanol gas as these older cars were not made for it.

Its a blast from the past. Ok it needs some work but this car diserves it. It needs some love thats all.

Hey Randy, If I remember correctly....I think Alex at Legit Street Cars purchased after market wheels for his Grand National.

Great find Randy! So excited what your going to do this GNX!!

I would loose all the after market junk like that nasty boost gauge . That entire air intake system is wrong. That clamp is a no hub plumbing clamp for a drain pipe. The car itself is in amazingly good condition I would search for the original air intake. Great find Randy ! I absolutely love the t tops .

This street car has literally starred in one of The Fast and Furious movies, so it’s iconically noticeable to call a race car for drag duels🏁🇺🇸🔥 My brother does these types of old school cars well

It needs 36 lbs of air pressure in the front tires to make it run properly. I guarantee it. I love your videos. They're like the mechanics version of 'Shreds'.

Sweet find! Not many 1987 Buick Grand Nationals still around that are in that kind of shape. Nice work Randy. Looking forward to more video's.

Awesome job on getting it. Keep up the great work.

This is an awesome car! The cutting out is the mass airflow sensor and theres also probably a boost leak somewhere

Mann honestly i think u should look in California for grand national for 24k I think u would have found a seriously solid example..but imma ride along ..your channel is awesome 😊

Be careful driving the car without the MAF Sensor not being plug up. The car could be running lean while in boost which is dangerous for a boosted car. The fix for most of those cars to get rid of the MAF and go aftermarket ecu to run only a map sensor which is built into the ecu and make the car go from a MAF base car to a Speed density car which can run only a map sensor. That is big money to do all that work tho and you have to find a tuner.

Another great car that has been through too many of the wrong hands until now. It's now entering it's second life.

That GN is absolutely timeless, great buy! Greetings from Spain.

You’re going to love this one Randy way to go !!!!!!

3:05 All turbo Regals had A/C. And 3:46 355lbf.-ft at 2000 RPM. The only difference 86-87 was the EEPROM, which kept boost at 15psi vs. dialing it back to 13psi after a few seconds at WOT.

Congratulations Randy! I love it!

I had the pleasure of driving one of these years ago. It was so much fun..fast lol! Very nice car Randy.

don't fret of it, Ryan u got a really nice car ... the guy did what we all did at the time, not knowing it would be a collector. The temporary centerlines don't look bad at all btw, most of those problems seem mechanical. I can't wait to see what u do next to it. maybe u should start a second channel with the restoration and auctions on the other if ppl complain..just a thought.

Its like you took us to the candy shop with these back to back GM videos. Its always a great day when you upload. Awesome finds Randy!

I hope your having a great weekend randy love your cars they are so cool ❤

Here it is! The absolute dream car

With some work Randy she’ll be a great GN! Glad you picked it up! Yes it seems like it’s the mass air!

Looks great Randy! Those wheels look like you put the race track wheels on it. Lol! And yes, everyone would love to own one of these, me included. Still love my 87 Mustang I bought instead of it, but it is one of my favorite cars from the 80's. Hopefully you can get it running right soon.

My neighbor had a 1983 or 84 GN I was about 18 or 19 just out of HS I had just gotten my Cutlass at that time. Drooled over that car.

Keep up with the great videos mate. 👍 Mike from Scotland

Hi Randy! Try typing in "aluminum wheels for 87 Buick GNX" instead of Grand National. I found a bunch of them. I saw Classic Industries and avoided them. Please note: those wheels come in 15 x 7 and 15 x 8, with the 8s on the back.

The grand national is a great car for what you paid , the custom rear wheels are nice but if they are rubbing like you said you can just change them back to stock or aftermarket . Those wider ones will sell quick . I agree the air shocks got to go. A little work and you got a gem . Great purchase

Hello Randy I love that Grand National we will get it running very good

Great videos keep up the good work mate❤💯

ANS was a performance garage here west of Chicago. It specialized in GN's, Syclones, Typhoons and Turbo Trans Ams. Since it has the boost controller on it, it also most likely has a chip too. No telling what grade fuel you might need to make it run as is.

Wow that buick is sick !!! Makes that carlo looks a lesser ride… u Rock Dude ☝🏽

Both the Monte Carlo SS and the Grand National are two of my all time favorites! Great video Randy!

from what ive seen, the only option car is missing on inside is electronic touch climate control. and under the hood, looks mostly all stock, but you have a adjustable wastegate for the boost. be careful if you still run the stock fuel pump and its not "hot wired". usually most people run their own 12 gauge hot wire back to fuel pump as stock wiring doesnt deliver much power to it. this is almost a must to do when upgrading fuel pumps . also, the flex tubes connected the turbo to maf, most replace with either a polished metal tube or chrome tube intake. good luck and have fun with it, she looks nice!,, also, your brake light is mostly the "acummulator bulb" that is stuck on the side of the power master. this is most always the source of brake light. if thats not it, the pressure switch. and as a bonus, theres an idiot light on the right hand side thats not used, doesnt even have a bulb behind it its about halfway down the plastic panel that reads "power injection" , well i put a bulb behind it, and hooked it up to a boost switch that would turn it on at boost. yes this was a factory warning light that was never used on the gn, as GM was planning to put a water injection system on it to spray water into the intake upon boost. if you take off the dash and shine a light on the right side warning light panel you will see the power injection label :)

I had a 82 regal I pulled the wimpy 6. Cylinder and put in a built 70 455 olds engine in it. Passed anything but a gas station. Dynoed 538 hp and 673 lbs torque at the wheels. Fun to drive Bought the car in 89 from terry Staffords used cars in Pensacola fl Hopped it up a few months after purchase.

Another great one! My reason for subscribing to Randy's channel is because Randy delivers content of cars that I grew up around. Its nostalgia for me. Born in Atlanta back in 1988 and was raised in Buena Vista, GA (small rural town outside of Columbus,GA population 7,000 people). Well growing up in Buena Vista back in the 90s was a blast. I grew riding around in Chevy Luminas, Oldsmobile Ninety-Eights and Cutless Cieras, Ford Tempos, Buick Regals and Centuries, Pontiac Sunbirds and 6000s, Dodge Spirits and Dynasties, Chevy Cavaliers, Corsicas and Berettas. Randy maybe slightly older but Randy would be someone My brother and I would have hungout with back in the day growing up. 😊 But the main reason I subbed to his channel is because he delivers real life stuff for people who aren't rich.

I love your enthusiasm. Very good video. Thanks for Sharing!!!😊

Nice car, Randy! Get it ready for Power Tour.

Nice car Randy!!! The new wheels look great on it. Can’t go wrong with original or “period correct” wheels and raised white letter tires on an older car.

I said it before- now time for the G-Body Olds 442! I have been loving the videos recently.

Beautiful car mint condition congrats randy

That was an outstanding choice of automobile

Some friends that were stationed with me in the military, bought one brand new in 87. He would take his out and get it up to around 70 to 80 mph then shift to overdrive and the back wheels would spin. Gem of a car and is still one of my dream cars.

Excellent work getting a GN for the channel! Also, shocked that you invoked “LSC” in a video, but that video series was informative… kept up the great content!

Enjoy both the cars bud I'm glad to see them I can't wait to see what you going do with them thank you for video

Randy those wheels are AWESOME. Love this car!! Can’t wait for next video!!

Loving the G Body collection, Randy!

Great car for the Chanel love to see you bring this one back to its glory days

Love it all. If the alternator is not charging, look for the battery light. If that's not working the alternator will not charge. Finally a turbo regal. Awesome Randy!

Thanks for the video Randy can't wait to see this girl run smooooth.

She's a keeper.... very nice condition Grand National. 😊

A true movie! I’m so excited for the G body series! Keep it up randy!

Great find! I’ve dealt with ACV before plenty of times and found that a lot of car issues are aren’t discovered until after delivery. ACV is good overall.

Those new wheels do look awesome I also like the originals but new ones pop.

Good video & project Randy I like the temporary rims on the car good choice for the cooper tires can't wait to see what else you do to the car I love the G Body's & El Caminos The coopers stick to the road have a good day

That is an awesome car. I drove one brand new in 87 It felt like the front wheel lifted right up. Once that car is running good, you're gonna love it more.

Nice GN. I had mine for 14yrs, ordered from factory. Once I watched this a flood of ideas & fixes (and tips/tricks) came right back. I know this car inside and out, and then some. I already know the things you'll need to do to get it working 99.9%. Btw, I believe the correct governor specs are at 127mph before it begins to sprout its wings. I had the 1987 w/digital dash & a whole host of options (all the ones you have too & more). 0-60 in 4.7secs (mine). Change that intake & MAF sensor (and much more). The newer wheels look much better!! Have fun.

I would enjoy a bunch of repair videos its about to turn into winter in upstate ny 😅😂

I love it, it is so clean like holy crap

Thanks Rebuilds 👍

The video that I have been waiting for and probably a lot of other people

Love the new look great video

That grand national is absolutely stunning. I love that body style. I also love the body style of the monte Carlo ss you bought. I'm so envious.

'80 hella awesome decade....had so much fun.

Good choice getting right size tires and wheels.

This is going to be a great video series with all the little weird issues you’re having. Still seems like it could lead to a solid profit down the road. Those AR rims are better off on the Grand National IMO. I know they’ll eventually make it to the Monte Carlo, but looks so much better with the stocks!

Check to see if the mass air flow arrow is facing the right direction

Thats a great looking car Randy. I cant wait to get working on mine i just have too many projects ahead of it to get done. I feel somewhere around spring ill start on mine. Hope you have fun working on both your gbodys. They are great cars i love my ss and cant wait to love my gn. 😂

Great car looking forward to seeing a update on this car 👍

It says premium fuel on the dash. Great car.

Man what a beauty! I have a soft spot for those 80s GN’s! You’re definitely lucky to get it for that price!👌😎👍

You picked up two very nice cars at reasonable prices. Now all you need is an '87 Olds 442.

Rumor has it the "Big Al's Bike and Auto" is drooling right now 😎

Wheels look great. Hope to see more videos :)

This car is for real, and when you find a GN that is real ,you get it while you can. I think you did well with this special car!!

Try get in touch with Vice Grip Garage or maybe Junkyard Digs maybe one of them might know where to find the mass air flow for you that wont cost you a arm and a leg

My first car was an 87 Regal. I'd love to find one to fix up. I'm not looking for a grand national or a show car. I'll probably catch hell for this, but I'd probably v8 swap it and update the suspension a bit, but it would be my car so it would be my choice.

Classic Industries makes a 15x8 aluminum repop of those wheels and it shows that Goodmark has them in stock

winter jacket is back, great video!

Please LS Swap that Monte Carlo and use it for a power tour rather than the Grand National but if you get GN all fixed up it would be a worthwhile investment to keep

Looks like Granatelli sells compatible MAF sensors for less than $500, and LS ones with adapter cables for less than $300. Looking forward to this build!

That's not the world famous brown jacket. That looks like an upgrade to me 🤔
