Come on Brian, all that talk about saving money on the 4.3 from a guy who trades a truck in every two years. I buy every two years too, no matter how big a discount I get or good the trade in or what kind of truck I buy there's no saving money there. If for no other reason the V8 sound with exhaust is a good enough reason. If a grand a year is that big a deal the mid sized will save more money, pull the load and is faster. I own two V6 vehicles, one 4, one very old V8 all will out perform any new truck. The point there's really no real good reason for a V6 in a full sized truck, even tho it's a great motor, you didn't even buy one.

I didn't say "I" care much about saving money, obviously I'm not on a thrifty path through life. I'm just saying when faced with "There is NO reason to buy a 4.3l truck, including mpg" I have to disagree after buying one and using it a year.

 

If you're a young couple or single guy around $1000 a year can be money you think about. I pay that for my internet/tv/home phone now, saving that cash is like getting that stuff free. (or close to it)

 

I'm 50, I want my cars as quiet as possible now. I did the whole headers/cherry bombs on V8 muscle cars back in the day. These days I talk to friends and family on the Bluetooth and want to hear them, not the engine. When trucks go by me on the highway that sound like dump trucks I just look at the guy and think "Seriously? You find that preferable?". Would be like working with an impact wrench or chain saw, Sure, it needs to be done at times, but I don't shoot for racket like that whenever possible.

Eh. People were towing boats like that with the old 255 HP or less 5.7L trucks of yesteryears. And now a V-6 does it even better. No big deal.

We do realize that the ICE is a demand device…right? Motor only makes the power it needs to overcome the load running against it.   That said, with nearly 300 Hp on tap out of the 4.3 Ecotec3 those

I agree that we live in a "golden era" of car performance compared to the 60s and 70s.   What I'm saying is all this "5.3l performance is the stuff! Makes the 4.3l look like a slug!" is kind of a mo

Im 61, can't argue about the noise anymore. The only loud at my house is my old truck, once a wk the kid comes out to play, no more loud daily drivers since I was 58. Grumpy Bears single cab is a different argument, I was talking about big old 4 doors.

I thought about it more and I'd go one further:

 

I don't care who you are, saving even $500 a year matters. If you're a young father and sock that $500 a year into EdVest or similar when your son or daughter hits college you'll have saved a year of tuition and fees at a state school, minimum.

 

Anybody who has ever helped a kid through college (or couldn't) can probably see the value of having an extra year of tuition laying around.

 

A person has to look at the whole of their life, not just "Wowee, I can get that V8 sound for only a few bucks more a month!".

 

Easy trades that don't have relevant function differences can make for much larger long term gains.

Now THAT is saving some money with the 4.3l!

 

To get my 17.4mpg:

1. I had 3.42 gears, 4wd, Xcab.

2. I live a north of you in WI and had it in AWD a good 3 months of the year.

3. When water open towing 3000lb boat weekly, 4-5X a year 200mile+ trips

4. My daily commute was mix of stop and go city/short hop hwy, done twice a day. (ate lunch at home)

5. My dad tells me I have a heavy foot and stop too suddenly to get decent mileage or have tires last.

 

So, my mpgs may only be valid for me, YMMV.

 

Now that's the kind of usage I would expect to produce 17 mpg. Thanks for your honesty. BTW Dad might be right. :driving:

If saving mattered that much then maybe daily driving a truck shouldn't even be considered. You can get a good car for 15K and get 35MPG, and put your kid through college and buy them a house. I always used trucks for work when I retired I kept an old one around and daily drive a mid sized SUV that's gets 27 MPG on the HWY. Just saying if you need a truck not enough savings for a V6. I couldn't wait not to have to DD a truck, couldn't see the point unless I was working it.

There is a measurable cost saving to the V6. However, the amount saved isn't significant when you prefer a V8. I prefer the V6 and the money saved is a bonus! Arguing over engine size is similar to debating cab and bed length configurations. Our preferences have different price tags!

All this math and science....Can I just like my V6 truck because it's a good truck hahaha?

 

Sure you can. Just can't tell anyone why> :rollin:

This is a HUGE factor.

 

Even if the new 4.3 had exactly (instead of 10% less on E10, and about same on E85) the same power as the old 5.3 most of us drove, most here would be saying, "You have to get a V8! The new one has more power ! There's that V8 sound!" What if you suddenly decide to buy a yacht, how will you pull it?!"

 

On E85 the new 5.3 is within 5 ft lbs torque and 18 hp of the 5.3s we all drove. I've driven both and if anything the 4.3 on E85 felt faster and more powerful. Even on E10 it was hard to tell the difference because it made 90% of the last gen 5.3s power at the same RPMs.

 

We've all been conditioned to think "There's no replacement for displacement" to which I say:

 

1. Teslas don't have displacement and are some of the fastest vehicles on the road.

2. The high pressure injected, high compression 4.3 makes more horsepower and torque than a lot of larger V8s we drove back in days gone by.

3. Ferd's Ecoboost is getting higher than V8 power out of tiny V6s.

4. Small diesels, turbo and non, are beating V8s as well.

 

The saying needs to change to, "Technology trumps all".

1 clarification I think, the 5.3 before the 14 I had was rated 285 HP or close to it. The new one is rated 355 or 385 on E85 or close to it. That noticeable.

I get that the new 5.3s have more power than the old 5.3s and as such differentiate themselves from the 4.3s.

 

My point with 4.3s has always been that if you were satisfied with the old 4.8 or 5.3, you would likely be satisfied with the new 4.3 as it's very comparable. Personally I never thought, "I really wish this thing was faster!" or "I wish this thing could tow more!" with all the past GM, Ford, RAM full size trucks I had that had very similar hp/torque to the new 4.3l.

 

If I had wanted or needed more power on those vehicles I would have just bought it.

What is always interesting to me in this debate is:

 

If the hp/torque of the current 5.3 is necessary to have, why didn't most of us drive 6.2s in past generations?

 

Most of us drove 4.8s and 5.3s, and the current 4.3 is around the same performance of those.

 

So apparently that level of performance was A-OK in 2013 and before, but these days you need much more. Doesn't make sense to me.

The stigma of driving a gas 6 cylinder in a 'man' truck is enough to put many off.

 

What a girly-boy motor. (Said in my best Arnold)

I don't think there's a stigma so much any more. Most people who buy fullsized trucks for DD aren't as concerned with the small savings on the V6. Plenty of power for sure especially in the two door. This is an enthusiastic site after all, most of us here want more than basic transportation or we be driving a economy car. Most of the trucks I had in the past I put on power adders. My 14 was the fist time since the 90s I didn't touch the engine, I tuned everything but the engine. It ran so good on E-85. Every vehicle ad on TV has performance in it somewhere in its ad especially Dodge Ram. I even see old ladies driving hot cars these days, so there's the why.

      Joke Thread

      By Chuck FB · Posted

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
