What, you mean like making presumptions about an engine you haven't driven or owned? Funny how find a problem with my post but not your own baseless speculation.

 

Correct, I find no value in your opinion of the 2.7, you clearly think the 4.3 is the world's greatest engine so I don't know where you can go from there. Only downwards I presume. (Oh sh|t, another presumption, my bad.)

You misunderstand sir. I think the 2.7 a crazy piece of engineering. But I also think that motors this size belong in compact cars or S-10's or Colorado's. Can I hunt a bear with a 22? Sure, but why? As far as the 4.3 being the worlds greatest....yea...been pretty clear on that one. It's just really really good and no not perfect but good enough and with enough following to keep it awhile. This the current 'fleet' motor and every one I know that owns one loves it. Got a guy with a 5th wheel car hauler that thinks its just sick. The LV1 version is bread and butter in Fleet Vans. 

 

Everyone of you complained like little kids over AFM and that after you all settled down over VVT and thought that was too complicated and now you want to go to war over a motor whose cooling system is NASA grade? Get a grip. 

 

GM has been on this run of STUPID where nothing last even a product cycle anymore (5 years). Some of the motors that replaced the 3800 in Buicks had a one or two year run. 3900 for instance. Whatever some third world country has a excess of. 

 

Bet your to young to have heard of International Scout. Brother if you didn't have the metal tag off the part under repair the parts guy would never find the repair or replace pieces. One year they used distributors from five different vendors. Given the current GM climate this already beloved 2.7T is on the scrap heap by 2024/25 as will all of them. You think that motor will survive in a 2500/3500? So exactly what part of this would you be willing to argue to the death over? 🤨

This is why I told him one day to “get bent”. He offers nothing to the forum accept for belittling people and trying to make himself seem inferior to everyone else. A very sad old man he is!

And “he” constantly is bragging about hyper-milling a 4.3L truck for 30 mpgs is quite comical. I’d love to see numerical data on it, then again, nah, who cares. I have gotten 28 mpgs going 55 mph in my 2018 Sierra, but I’d rather get to where I need to go at the normal speed limit. I can afford the gas!!

A 4x2 regular cab WT with a 3.0 diesel would be pretty fun and get pretty good gas mileage I’d wager.

I’ll see your bet and raise you a 6.2 in that same WT, preferably with a 6.5’ bed. Then offer it with the LT4 as a $5k upgrade.

Yeah. Not happening guys. This ain’t Ford where you can get their top engine choice In a basic XL model. Just don’t get the games GM plays.

Yep he loves to go around pretending that 4.3L is the savior of mpg and capable of anything this “NASA grade” engine is, when he changes the oil weights to specs that makes the engine unusable at max capacity, hypermiles his speed, and does other modifications in his thread to get that number. It’d be fine if he at least but a * disclaimer around his numbers and otherwise just quoted the fuel numbers that he got in his first month of ownership.

I’m considering picking up a 2021 F150 2 door V8 just to mod it out and have fun.

I try to be nice, but he just seemed to berate the person unnecessarily just because they got a 2.7. He seems to have some good information in his thread, but there is no reason to go around beating on people in a forum because they disagree with you. Imo.

The entire 135K life of the truck in numbers. Summer 2019 30 mpg every tank for six months.

Live time average nearing 28 mpg. Just a few tenths short.

I don't berate people. But I have no use for stupid.

The one thing Duct-tape won't fix. 

 

As far as getting where your going. Life time average 42 mph miles/hrs.

It ain't bragging if it's true. 

 

And what have you to back up your mouth??

You have plenty to say about me being this way or that and yet

it's just fine for you to be an a$$

Well ain't you all that. 

Hypocrites

:wtf:

Nope, you proved duct tape won’t fix that. That’s why you posted evidence backing up what they said regarding hypermiling.

However you're probably still missing key points, such as that 5.3 "brother" is also getting dropped (both the 4.3 and the 5.3 with AFM). Think it's obvious, emissions and/or mpg aren't there for these engines. They upgraded the 5.3 with DFM but the 2.7 destroys the 4.3 so why bother upgrading it? They can also use the 2.7 in more cars/trucks, so it's a better fit in the lineup.

Educate yourself. Ignorance in one thing. Willful ignorance is quite another and when you attack in willful ignorance and call me the the bad guy....yea....whole different game. Stupid. So yea... I'll get sideways and call it what it is. Put on the big boy pants. Next!

The guy was just sharing how he was happy with his truck and his 2.7. Leave it to one person to trash talk his engine and start a shitstorm when he didn’t ask for the opinion in the first place. Again. We’ll never have to wonder why new people don’t stick around here.

One of the biggest mileage killers is drag. Since retirement I’ve used 5 vehicles in 6 years. Just talking HWY mileage at 72-74 MPH. The average MPG are. 14 GMC 22, 15 Hyundai Santa Fe V-6 27, 17 Toyota Camry 2.4 27, 15 CRV 27 MPG. 11 Genesis sedan V-6 27 MPG. I can’t imagine at HWY speed the engine in these trucks are that much different. The wind drag doesn’t change. I did notice big mileage changes at lower speeds. Obvious I know. Cylinder deactivation at HWY speeds didn’t seem to make any difference through many cross country trips. I believe in controlled testing it bought GM some gains. At the expense to the consumer when (if) they fail.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
