Lol.  I know.  I mentioned the 6.2 because it was brought up earlier.  

 

And a a well tuned 2.7 F 150 has run 12.87.

Some of you guys are ridiculous. The dude got a new pickup, and that’s awesome. Some folks can’t even afford a $5k used Nissan Altima. If he bought a truck to haul limbs from his yard twice a year, so

We get it, Skippy.  We know where you stand on the 4cyl.

Congrats OP - let haters hate. Your rationale behind picking the 2.7T sound logical to me... Not all of us regularly have to displace fallen trees from seemingly major thoroughfares. Keep us poste

For me, I’m a V8 guy all the way, not to much interested into performance mods, did on my 18 6.2 cause I lifted it and needed to recal it so I thought what the heck. I LOVE the no noise and low rpms from driving a V8 on long road trips. I was interested in a Raptor if and when I start having issues with my truck (none so far, knock on wood) but I just can’t get over that queer little exhaust sound coming out the tail pipe, then I looked at the Shelby F150 and it didn’t do much for me, got back into my truck and liked my interior MUCH better. I hope everyone gets what ever their hearts desire but for me, I’m old school, low rpms and a V8 throaty sound will put a smile on me on every road trip. Btw, there are a couple Denali guys on the forums that have done an enormous amount of work on their 6.2’s, spending more time in the performance shop than actually driving it, not for me. I truly believe that running a small engine hard for long periods of time WILL only bring breakdowns sooner rather than later especially with a purchase intention for quarter mile and racing it only comes to mind.

I agree.  I like my 6.2 a lot.  It’s kinda fun to drive for a truck.

Not the most scientific test but when I pull my trailer I set the cruise on the highway to 70mph. On overpasses and bridges my 2.7 with the trailer never downshifts going up. The 5.3 would downshift. Which would mean its downshifting to generate the torque it needs to maintain 70 mph and having to rev higher. Meanwhile the 2.7 is still in 8th gear purring at 1500 rpm at 70 mph.

What are the differences in the transmission? What were the rear axle ratios?

That's what is gonna dictate whether your transmission shifts, not the engine.

I guarantee the 5.3 is geared lower than that lawn mower engine with half the rated capacity.

 

Lower gearing WILL make you shift more to maintain speed, but I hardly consider that a negative on towing ability. Look at their ratings. The 5.3 trucks will tow twice what the 2.7 will.

 

Here's a test.

 

Get a trailer loaded to the max that the 5.3/3.42 will tow, and put that on the 2.7.

 

Now tell me which one feels better.

Wait, you’re pulling 7k# trailer with your new 2.7 4 cylinder correct?

The V8 will want to roll at the highest gear possible for better MPG. Of course it downshifts for a hill.

Your 2.7 won't because it's already spinning high and more revs only help.

But that downshift on the V8 with the gearing it has will give it far more torque than your little 2.7.

Waiting for a shift isn't a measuring point.

Both had 3.42 rear axle. The loaner had the smaller 18" wheels and tires while mine has the 20's. I guess technically mine would have the higher gearing with the bigger tires.

Not questioning the 5.3 having a higher rated towing number. Just stating that for my usual towing the "lawn mower engine" struggled less than the 5.3.

Nope. Just a trailer with load of about 2000lbs.

How is it already spinning high when in the example I gave its only around 1500 rpm? Are you getting the turbocharger and engine RPM mixed up?

Max towing is rated at 6700, need I say more!

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

      By Atlas · Posted

      I think we're reaching the end of constant projects/work.   The water pump bolt appears to have self-sealed, as it's not leaking anymore. I'll take it, and, I'm ready should it self-unseal! I was also getting an oil leak at the front oil pan seal and timing cover and came to find a pan bolt on the corner wasn't even finger-tight. Too easy. And, it was. But, it appears tightening it has reduced a leak producing spots on the ground every time I parked, to just a weep, leaving an occasional dot on the cardboard that lives under it while parked. That's acceptable on a 30 year old engine in my book. I do hate leaks, but, replacing the pan seal is quite the job.   The rear washer line is reconnected and the sprayer works, although getting an intermittent washer fluid drip off the bottom. I think it's just residual...the reservoir filled up the channel in the rear floor and drained down into the upside-down spare tire/wheel. So there are residual puddles all over under there, will wait a few days for it to spill out and dry before I go chasing a potential leak.   The door speaker...no dice. Speaker works just fine, it's that channel in the factory amp that's gone bad. Can't win 'em all. And, whomever buys this will probably tear out the factory radio for something more modern anyway.   I put about 110 miles on it yesterday. Put a lot of wind and heat into it with some mountain driving. Still runs great. Near the top of the pass I got off on a gravel side road and put about 10 miles on with 4hi engaged. Works great.   If ya squint, she's mint! God I wish these were still in production. I can see why they're not. They're rudimentary bordering on agricultural. They began life as a pickup truck and then modern society demanded the rear be enclosed for kids and crap. They're still a pickup underneath, and that gives them lots of ride character, sway and bounce and bump steer. They're alive on the road, and, at least for purposes of nostalgia, it makes driving one a lot of fun.   The Check Engine light did come back on the pass, P0134 for the upstream O2 sensor dropping out. Putting heat into the exhaust causes it after about 10-15 seconds of increased load at higher RPM. The downstream sensor is completely mangled (someone clearly had a rough time removing it, but they didn't replace it?) so I'll just put two in it. For what, mostly to cure the CEL, I can tell the cat is damaged. It's not plugged or fractured, but it's not catalyzing. There's some guilt in not fixing it, but at a cost of $500+, the truck just won't get driven much under my watch. I dislike the smell...running the truck in the shop even with both doors open and the overhead fans blasting, I still reek of pre-cat exhaust. Sticks to clothing and everything else.   Window motor (I'm dreading this), and tires, and that should be about it. 50/50 on Starfire Solarus H/T's, or spending $20 more per tire and going with Cooper Discoverer RT's. I like the look of the RT's a lot more, but is it worth it? I've got a really good (just very old) Toyo Open Country XTX on there now and I like it.

      Shift to Park Message Warranty Claim

      By tjonesdfw · Posted

      From what I've seen, they "could" sell the switch but designed the assembly such that the switch can't be readily removed and replaced without removing a plastic locating pin.  Sure appears aimed at forcing the end user to purchase a $900 shifter assembly instead of a $20 switch.  Thankfully I still have some extended warranty left...  this one has had warranty repairs almost every 5K miles from the day I bought it.

      2021 with Intermittent AC Cooling Issues

      By tjonesdfw · Posted

      I'm well aware of the typical bathtub failure curve, but plotted, this truck has been more like an elevated straight line.  It started days off the lot with misfires that GM couldn't solve for almost 2 years, and steadily continued over the last 5 years with repeat replacements of wiring harnesses, camera modules, cameras, parking sensors, head unit, rear windows, rear leaf springs and bushings, lower control arms, a radiator, and now an ac compressor and a column shift assembly.
