Just read that V6 engine will put out 305 lbs/ft and 285 HP. Not bad for a V6. Probably has to be screaming to get those numbers.

It okay...I was expecting 300 hp though. Have you heard what the fuel mileage is yet?

Thought the 4.3 would be pushing 300hp also. I see the 4.3 holds 6 quarts of oil where the 5.3 & 6.2 hold 8 quarts interesting.

the power comes on lower than expected and the torque is available in a lower rpm range than the 5.3

Have not read the link above yet. But for reference or a reality check. The all new 5.3 V8 in 1999 was to set the world on fire with 270 hp. They bumped it to 285 hp for the 2000 model year(do not remember torque specs that far back). Current 5.3's are at 315? So kind of thinking 285 out of a 4.3 to start is pretty good.

 

Edit: adding link comparing current hp/torque numbers...

Where do these higher HP numbers on the 5.3 on E85 come from? If they are true why is GM not stating them?

 

I thought that the 355 HP released number was weak. I don't care what the 5.3 used to be rated at, they could have made a 5.7 or 5.4 or whatever. They probably used the same 5.3 for sympathy so loyalists would look at it like an improvement. B.S.

 

Those jackasses have had plenty of time to build some quality engines. Their competition has much better numbers. The new Chevy LTZ 20 inch wheels look like they made something for DUB magazine.

GM is stating them. The link Hodges25 posted above is straight from GM. And GM makes the best truck engines in the industry. Fords used to be slow, spark plug spitting slugs and the new 5.0 blows apart on Mustangs with mild power adders.

I love GM engines. Totally agree. Had not looked at the link. I have been pissed since they announced that 355 bull. Glad I can count on some extra ponies.

 

All I can say is that I hope they keep E85 in the taks for the test drives!

It's amazing what GM does power wise with their engines with such a simple design. Sure the 5.3 makes a little less than Ford's 5.0, but Ford has to use a more complicated design to get just a few more ponies. Same way with the current 6.2. GM's is a pretty simple setup while Ford uses 2 spark plugs per cylinder and a bunch of other useless garbage, and it doesn't really have that much more power.

My brother and I recently pulled two new 7X26 foot enclosed trailers from south GA to SC with my truck and his new Toyota. I rode a fill up pulling the trailer with his UGLY yota, and he in my Chevy. I was ashamed after getting behind my wheel at the next stop. Gutless came to mind. He also avg'ed 12 mpg to my 9. Sad.

 

Still a Chevy man though!

      Gas Prices

      WTI futures / speculation is just that. WTI futures <> current 4-7% inflation and national average gas price over $4.00/gallon.   The spot price, at delivery, is currently $87-$95/barrel which is why gas prices remain high.   Edit: oH mY gOd mEnTaL BrEaKdoWn In tHE pOsT aBOve mInE.

      He does, actually. In another unrelated video he mentions the president called him in the middle of the night to relay some information on a cause (religious based) that he's invested in. Glenn expressed concern that another leftist administration could wield too much power with some procedure the Pentagon was using, classifying certain religions a certain way. Being that he is LDS (Latter Day Saints), he gets hate all the time from ALL over the political spectrum, so he's invested in this. Trump called him back at 5AM to tell him he had made some changes to that classification.   So, yes, they are and have been in contact regularly since the start of the administration. Glenn, of course, always asks his permission before discussing anything on the air.   I already spent an hour or more just searching for these videos. I may have my numbers wrong - I'm not a numbers guy. It may have been a MILLION barrels, not 1.5. The point is, our President, by his actions, gives a crap about America, and US - this is completely OPPOSITE the actions of the prior administration who projected hatred for anyone who wasn't following the left's edicts in lock-step.   Remember, they called January 6th an "Insurrection", when there were ZERO weapons among the crowd, undercover FBI agents agitating the crowd, along with paid leftists acting as aggressors, egging the crowd on in an attempt to whip everyone into a frenzy. It's all been proven.  Pelosi refused Trumps request for more National Guard troops. This smells 100% like an inside job for those with critical thinking skills. Only a handful of guys in the crowd got wrapped up in that, thankfully, but EVERYONE was searched out based on cell phone data, and charges were brought against many. And 6 or so people were locked up and left in solitary confinement for YEARS with ZERO due process!! If you give the slightest crap about our Nation, REGARDLESS of your political leanings, this should frighten you to your core. This is what men suffered, bled, fought, and died against 250 years ago!   This has gone FAR BEYOND left vs. right. This is a  threat to America, and our way of life. This is PRECISELY why Trump, a BILLIONAIRE who could have chosen to take Melania and sit on some tropical island that he could afford to buy himself and RELAX, instead chose to run for office, get hate from literally every corner of the media, get ATTEMPTS on his LIFE constantly, and begin to repair some of the severe damage that's been done to this Great Nation.   I don't know why I bother wasting my precious time here. Everyone has their minds made up. They won't realize we all were correct until it's too late ... after they elect another tyrant that hates America to office (Obama), or another puppet whose administration is secretly running the show behind the scenes (Biden).

      DTC P2C48 auxiliary cooling pump

      By Newduramaxh*ar · Posted

      Hello, Im in a bit of a bind maybe someone could help me out.  We towed our trailer, up a pretty steep incline (395 north of Bishop) done it before no issues. I got to our campground turn truck off, i restarted the truck about an hour later  and check engine light turns on. Found DTC P2C48,  unable to reset.  This morning i removed the plug, there's 12.12v at the plug. Reservoir near firewall is full of coolant, checked for leaks nothing. I dont hear or feel the pump turning on. My dilemma, is nearest dealer  is 4hrs away that has the pump instock. Is it safe to drive? By me checking the available voltage at the connector and not hearing/feeling pump turn on, is it a bad pump? Please help...

      The figure bandied about is "100 million barrels" so I think a decimal is off somewhere. But that doesn't change the outcome much when the expected flow through the Strait through over the same time should have been more than 2,000,000,000.   So 5%, if that number is even true, and there's sufficient data to believe it's not. Give that man another Fifa peace prize! 5% is less than the flow of a grapefruit-sized prostate blocking the release of cheap lager after a night of bingo.
