The Chevy Project Might Be Hiding a BIG Surprise, Or a Ruined Engine | Here's What We've Learned!

[@billp5424]

The ingenuity of the American farmer/ rancher never fails to amaze me.

[@fl_atv_riders4455]

a g80 is a open diff until engaged its a clutch locker so the tires will spin in opposite directions until enough slip is detected

[@MrBillsfishin]

If I could borrow David for a couple of weeks to help me get some work done on my truck. You are amazing sir. Such a tremendous work ethic.

[@kevinbarry71]

This guy needs his own KZbin channel. Wait, he kind of already does

[@stevenrogers2457]

He already does, it's called Going Off The Rails. Check it out, David is a cool guy

[@dustinherrell9610]

He reminds me a lot of my dad he always has creative ideas

[@rlessmeier]

Save jolly rancher for a more colorful truck.

[@alvernonjunior1701]

Yeah, the 2021 Silverado

[@joeychaseable]

Thus guy needs to be on the TFL payroll. I'd like to see him in more episodes.

[@ChrisXif1]

Man, David is a class act. Smart, kind, practical guy. Glad you've been able to team up with him.

[@hgtydjdjdgh67889]

This is my favorite video series on KZbin right now (or the abandoned mansion). I will admit, I'm a huge GMT400 fan so seeing this go together is very interesting.

[@bpeeps00]

David is great. He talks and acts like there’s not a camera in his face. You can tell he’s a real dude.

[@joeychaseable]

Tommy seems to be in just about every video on all TFL channels... Working hard to be sure content is out there... I like it! A lot of the younger generation don't seem to get that part about life yet. Keep up the hard work Tommy Gun! Show your generation the way it's supposed to be done!

[@a_man_has_no_name]

David is such an awesome and talented person. He's very handy and can get things done with very limited resources. keep up these series with David. Much love and respect

[@kieranlavoie8124]

G80 lockers only activate when you get wheel spin. Try turning one tire forward really quickly if it has a g80 then you’ll head a snap and your tires will lock

[@nkoeppen]

David is one of the coolest people on KZbin!!!

[@davidmcdowell7791]

That 454 is likely a GM service replacement. The aluminum valve covers without 454 emblem, the manifolds with the slits and the driver side manifold mounted oxygen sensor. It was very common for the TBI 454 motors to have the cam go flat and they were commonly replaced. You can decode the Julian date on the block back by the head. The rear end G80 will only rotate both tires when it is in the locked position - the two tires need 200-300 difference in RPM in order for it to lock. Put the truck in neutral, have one person hold a tire and spin the other one as fast as you can. You should be able to get it to lock. You can also take the VIN to a dealer and they can decode the RPO (regular production options) for you and will be able to tell you the gear ratio and if it had a locker, among other things. The difference in the door is due to interior changes - the burgundy door you installed is from a 95 and new GMT400. The inside stamping is different, and the exterior handle is different as well. Awesome to see this truck getting some love! The GMT400 trucks are my passion, so it's awesome to see. Keep it up!

[@JGUNW1R3D]

David deserves a regular segment ... or just keep doing this type of stuff I guess. David’s great and I get a kick out of him turning someone else’s junk into gold.

[@mikebelcher5111]

Those big heavy doors are famous for dropping, I have a bar (homemade) to lock around the latch pin, and hooks in the latch mechanism allows you to pull it back up were it belongs . . Love these bodystlye Chevy. Im still amazed the cab corners are solid thats something u never see. Can't wait to see this beauty done...

[@ShukenFlash]

I love these DIY projects with David. Watching these makes me want a garage/barn like that and a project truck

[@DaddyDan77]

This is going to be a nice, hard working truck when finished. Scottsdale was my favorite trim package (back when the trim levels had names). God bless the American farmer.

[@badgerpa9]

David is a good man. G80 doesn't kickin until you spin some, my Yukon will do that also but if you have second person grab the other side and spin back you can get it to click in.

[@2500mike]

GM wasn't big on cab lights were they. This truck is going to come out great. The year appropriate wheels are going to look so much better. Always enjoy these videos

[@nc2827]

Must have been an option, my 2500 has them from factory.

[@buddy8225]

Sweet. Never knew Chevy doors were different from year to year. Cant wait to see what’s next.

[@johngibbons9239]

Had a 97 1500 6ft bed with the 6 cylinder engine used it to mow grass with for my buisness was slow compared to my 04 f250 but I liked it never left me stranded.

[@mt1885]

GM small-block and big blocks along with DIESELS are the BEST as interchangeability of parts as well as they last the longest.

[@Kcducttaper1]

8:12 That doesn't work for the G80. The G80 is a regular open diff until the difference in wheel speed is greater than (some threshold that I don't remember). What you need to do is jack up the rear end and have someone hold one wheel (lightly but firmly) while the other person gives it a little bit of throttle. You could also shove a doorstop under one wheel or something like that. I didn't think my Trailblazer had a G80 in it for over a year after I bought it, but turns out it for sure does!

[@benr8071]

I need a new y pipe for mine. I fully restored just about everything on it. 2 tone red top and bottom and black in the middle. Motor and trans in those trucks are just about bullet proof

[@albrown8890]

My TBI 350 was running rough at 177,000 miles. It was a worn out distributer. Got over 200,000 now.

[@benr8071]

Mine has around 233 but the odometer stopped working like ten years... who knows lol

[@tman1129]

Great series. Love seeing David on the channel! BTW, plastic parts are actually chromed in almost the same way as steel!

[@JoseAlvarez-kb2io]

Awesome job David! Can’t wait for next video

[@michaellaun]

Really like how this is shaping up. Looking forward to future episodes. Adding David to the team is a much needed skill set to TFL. He keeps getting better on camera the more time he gets. Thanks TFL!

[@danthompson1467]

I like this guy ! he attacks the projects like I do nothing out of control just just to the point

[@roberturban2934]

Love this channel ! The others too, but I wish you continued success here! Nice break from the garbage being produced! Great job Tommy!

[@nevco8774]

David is getting gaps on his historical truck better than on new Teslas! Good job!

[@matthewbarnhill5402]

My '94 Olds Bravada has the "G80" RPO code but the original window sticker calls it "Posi-traction." Both wheels pull all the time regardless of traction so the code could vary more than the newer G80 code we all know.

[@EnglehartProductions]

I would get new weatherstripping for the whole truck. You can go to a pull-a-part junkyard, pull your own weatherstripping that’s in good condition off of a truck, and only pay $20-$30. I got a complete set of weatherstripping for my 04’ Cherokee for $20.

[@joshroden6708]

Out of all the channels you guys do these truck flip series your doing are sweet keep it up!

[@danmagill7616]

Keep these videos coming Tommy, just about every guy has always envisioned about restoring some type of old vehicle.

[@jewllake]

The posi test is true for a posi limited slip clutch pack. The G80 is a locker. Jack one wheel up in the air and put the truck in neutral spin the wheel as fast as you can it should lock and kick your hand back. You can also jack one tire up and spin the RPM slowl in drive with the engine on and you will feel it kick in - just be ready to hit the brakes!

[@rickoffermann7156]

When you spin a g80 equipped rear wheel, the other wheel will spin in the opposite direction, unless you spin it fast enough, then it will suddenly lock

[@danielrodriguez5847]

I believe there was a design change on the doors after 94 and that's why the inner door panel didn't fit but other than that I can't wait to see how this truck turns out

[@davidmcdowell7791]

Yup, after 95 the doors changed to accommodate the new interior.

[@habanero8192]

Tommy: a gooseneck is not a 5th wheel ;-)

[@johnhiggins3943]

Great video to watch taking a quick brake from working on my little Chevy work truck

[@michaelbudlong3805]

If you have a G80 you have to spin by hand the tire like you did but faster 100rpm difference to activate the locker. If you do have a G80 the wheels will lock for a second when spun fast enough. I know this I own a 2018 Chevy with G80 and I spun one rear tire increasing momentum getting it faster and faster and the wheels lock for a second and the tire stops immediately.

[@brianrocco4301]

This project truck is awesome! Keep these videos coming!

[@thethepills]

paint the rims the original silver. You have a gorgeous specimen there sir. I have a 96 like that. I have had it for a long time, best truck ever made!

[@mikeh4547]

When you showed the rpo code sticker, it has the code L19 which is the factory tbi 454 code from back then. I have a 93 1 ton that is the exact same way with the exact same code

[@mycoolkeno]

Not that this is a Z71 package but Chevy's that have the Z71 package have came with skid plates, G80 Locker and rancho shocks. I have had several vehicles with a G80 Locker and have had nothing but good luck with them. My stock 99 sierra has one and made it through 14 miles of trails last winter in 2 wheel drive when a stock TJ wrangler had to be put in 4 wheel drive several times that day. Makes a world of difference in traction.

[@egroach77]

I'm not one to disagree with David, but the g80 will operate like a open diff when its up on jack stands. My 2 silverados did this same thing and they both had g80's

[@robb1165]

Not quite. It will be the same when turned slowly. If you spin it slowly then jerk the wheel the other side will lock and kick back. Or if you hold one side you can get it to lock.

[@davidmcdowell7791]

@@robb1165 they are fully open when unlocked, the have a set of clutch packs like a limited slip with a ramped gear, so once the wheel speed difference is enough it locks and the ramped portion moves to press the clutches together.

[@robb1165]

@@davidmcdowell7791 That is why you can lock them when doing a test on the jack stands by suddenly increasing the rotation speed.

[@Trdbrglr75]

@@robb1165 I believe it’s 100 rpm difference causes the lock to occur.

[@matthewshambler2644]

Seeing this old truck getting brought back to its former glory is awesome! There's an Afrikaans saying that says " 'n Boer maak n plan" which translates to a Farmer can always make a plan/work it out, this is very true here..

[@ronaldarchibald2506]

Had a 1990 454ss that the distributer wore out also. The valve covers didnt say anything. Also had the locker in rear.

[@itsyaboibdb1369]

My 1996 Chevy s10 4x4 has the RPO code for a G80 locker and I’ve seen from off-roading, especially in the sand that both rear tires do spin, but when I lift the rear off the ground the wheels do spin in opposite directions like an open diff so you should pull the diff cover off to see if someone put one in that 14 bolt. My buddies 2007 z71 4x4 GMC Canyon has the RPO code for a G80 as well and when he lifted his rear off the ground the tires also spun in opposite directions like a open diff would.

[@jakematthews6982]

Does the exhaust manifold on the other side have the split between the ports? If not then maybe the driver side manifold was replaced because of a likely crack with a later updated one. Check part numbers.

[@timothyhays1817]

Just to let y'all know a G80 is a open diff function. So the simple Jack up and hand spin test won't tell. Now with out rpo code and without pulling the cover. Raise both wheels off the ground. Start engine put vehicle in gear. At idle slow one wheel down. The locker will engage when the difference in wheel speed meets lock up conditions. There's lots of good info out there just look it up. The Old limited slip systems you can tell by the method they used in this video but not G80 style of lockers.

[@Mike-eh3ty]

Coverlay Mfg makes a nice set of door panels for that truck you might wanna see if they would sponsor that truck @TFL

[@shadowzinthegila1663]

Love the old chevys

[@bretc9644]

I think the 90’s produced some of the best looking American pickups ever produced. All three manufacturers were really on their game.

[@OnkelPHMagee]

How plentiful are GMT400s in salvage yards there? Would a replacement bench (or buckets) be cheaper/easier than recovering the original bench?

[@blueduck9409]

Rough running engine could be distributor, EGR valve, the o2 sensors, cam shaft, timing issues, spark plugs, vacuum leaks. At least thats what i always start with.

[@justinkeckhaver8199]

Don't quote me, but I'm 99% sure that after 1990-ish all the 454s got the "styled" aluminium valve covers, and not all of them said "454 BY TONAWANDA".

[@GKMess42]

Hooray for keeping it original!

[@DeadmanR68]

Eaton G80 (grenade 80) has a pawl that activates when the rear wheels feel either 150 or 200 rpm difference from one another which activates the pawl engaging both wheels granting you limited slip. They call them grenade 80's because when the pael engaged they sometimes explode. So Powderkeg is a fitting name. 🤣

[@8__D]

Lol they only explode when some kid does burnouts in the high school parking lot. If you don’t do stupid stuff like that they’ll last forever

Could the replacement door be from a 95+ GMT400 with the interior refresh?

[@dustinherrell9610]

Love seeing David in these videos

[@kevin9c1]

Or they just replaced the exhaust manifolds with aftermarket. The driver's side had a bung and they didn't find anything better to fill the hole with than a random O2 sensor. I think it's M18x1.5 and I think lots of things fit possibly including a spark plug. Or get a proper plug. For the valve cover...who knows, could just be replacement valve covers, too.

Isn’t the g80 technically an open differential when not engaged

[@woffordsoverlandjourneys8618]

the g80 differential will spin the wheels in opposite directions until you spend them faster and they lock and go the same direction

[@cougarwildcard2768]

If you got more time than money, just take that old grill and color-match it!

[@jlsgarage872]

Go back and spin that wheel faster in the air because the g80 needs one wheel spinning a certain speed faster than the other to engage. Its not a true limited slip.

[@8__D]

I agree the test wasn’t done right, but if it doesn’t have the rpo code it probably doesn’t have a locker

[@kristoferfc6525]

Not how that works for the rear end, it needs more rotational speed to lock, my G80 spins like that too at that low of speed
