Questions For Guys With The L9h And An Intro.

[Badass69]

Hi everyone!

 

This is my first post but I may as well just start off by getting down to it. I am not new to GM by any means, grew up with them and play with them. I actually have a company provided 09 GMC 3/4 ton with the LY6 and 6L90E..... I like it other than the transmission shifting. It's not bad but it has an intermittent flare between 2nd and 3rd that the dealers are blaming on my roof rack and 265 tires ( stock were 245/75R16). I don't care much and they will warrant it if it grenades. Tuning would fix it....... but I am not doing that on a truck I don't own.

 

Anyways. I just sold my 2009 crewcab short box Laramie Ram 1500 4X4. New body style of course with the Eagle 5.7 and 392 gears. I sold it because I hated it so much I could hardly look at it. The truck was a turd....... plain and simple. When a bone stock over 200000 mile 97 Vortec 350 powered extended cab s/b 4X4 with 373 gears can hang with me......... not so much. No low end torque at all...... The truck was torque managed to death but the 545RFE is a weak transmission and pretty needs all that to live. I made a bad move, bought the truck and then complained about it for 10 months until I finally got rid of it. Didn't do too bad and really didn't lose a ton on it.

 

Now the point of all this. I like power, plain and simple. I test drove 2 L9H powered crew cabs before I bought my Ram and wasn't overly impressed with them. That being said they both had 342 gears with 20's on them and of course were loaded crew 4X4's.

 

For 2010 you can get the 6.2 in an extended cab, not just a crew cab. From what I see you can also get them with 373 gears, even as a 2wd with the Max trailer package. Now from reading on here I am seeing guys with 2wd Denali's, even tuned that can't break the back tires loose and are soggy down low. Is that what I am too expect? I hope not. Between the 4.02:1 first in the tranny and a 373 gear..... the truck should be able to destroy back tires and pull pretty hard. Otherwise what's the point. I want something that I can tow a smaller car trailer with and do not want a Duramax, Cummins or Powerjoke. It's not that I just want smoking tires..... I just like enough low end torque to get a truck moving like it should. That Ram was absolutely pathetic and had no low end at all. It only started doing something at over 4500 rpm....... kinda completely useless in a pickup truck. I know the 6.2 is rev happy too but with over 30 more cubic inches than my Ram and in a lighter package with more gear one would think it should pull. I will tune the truck right away as well....

 

So how happy are you 6.2 owners out there? I want a truck that I can tow my car to the track with occasionally and even run down the track with itself occasionally. What the general consensus out there? Or am I delegated to sticking with my LT1 powered 96 Caprice, lol.

[Badass69]

Ok, maybe I will simplify. My future truck would be a 2010 6.2 powered extended cab short box ( flip flopping on 2wd or 4wd) Max trailer package truck. How happy are you guys with power in the lower rpm on a 6.2, especially after tuning is done? I want a truck that can actually spin it's back tires....... unlike my Ram. That and pull a smaller trailer properly. Put it this way..... an average TBI or Vortec 350 would work that Hemi from 0 to 30 mph. Then the vortec 350 just ouran mine altogether, hence why it is gone. That's just plain wrong, torque managed or not.

 

I will be tuning my truck, either via Westers( local to me) or maybe Campbell automotive. What can I expect? Big horsepower numbers are pretty meaningless to me when you take off like a 4 cylinder Honda(exaggeration, lol)....... If the truck needs a 3500 rpm stall to launch with any authority...... that is kinda defeating the point of it being a truck. I would be happy if the low end power was like my stock 9C1, LT1 powered Caprice, for comparisons sake.

I love my 08 denail. I usually have no problem barking the tires on mine, resulting in the traction control activation even with the 22's that I am running. I have had mine tuned via a dyno and it was outstanding, unfortunatelly due to some issues I had to return it back to stock as I dont need my warrenty void. I am currently waiting on a seperate new ECM so I can have it tuned and if any problems come up I can return it to stock. I think the 6.2 w/6speed and 3.42's is a good combo, fuel economy is not too bad, it gets better then my 05 silverado ss with the 6.0 got. I could not imagine it with a 3.73 rear end. I have yet to see anything saying they are going to put the 3.73's in them. Check this site out on the specs of the 2010. I only see the 3.42 paired with the 6 speed.

Thanks for the response. The Max trailer package trucks had the option of 373 gears with the 6.2, in 2009. Special order only I believe. Now for 2010 I was getting my info from the GM dealers option system. On GM.ca it only shows 3.08 and 3.42 gears, but the dealers show 373's as an option with the Max trailer package for 2010 as well. It's funny because the 6.0 litre is gone altogher and the "Vortec Max" so to speak is now the 6.2. My 09 3/4 ton has 373's behind it and I really like it. I thought first would just shortshift but it actually doesn't do too bad. It runs really strong actually. That's why I want the 373's. Plus with the two overdrives and .66 being 6th, the rpms stay down nicely on the highway.

Like I said, that site only shows 3.08 and 3.42 as well, but the updated 2010 option list for the dealers still shows 373's available. I like that I can get an extended cab with this engine now. That and this only has 17" rims with 265/70R17 tires... smaller and lighter than either the 18's or the 20's. Actually I would love a 2wd regular cab short box....... but I don't see that happening.

 

For reference sake, this is a stock order truck from an inventory search.

Notice that this truck shows it's a max trailer package GMC crew...... with 373 gears and the 6.2. I think that would be awesome for playing with.

[mjdxtreme]

I am sure the 3.73's would be killer with that setup. Gas mileage may suffer a big hit on highway driving and even in the city more so that it already does. I get between 12.5 and 13.5 on city driving with the 3.42. I would assume you would lose about a mile or so per gallon with the larger gears.

I would hope so! The LY6 in that 3/4 ton I drive is pretty snappy down low, even all stock. It has 31" tall tires on it, so nothing extreme in that sense. Mileage....... meh. I can live with whatever as long as the truck has power to back it up. Well more than 10 mpg would be nice, lol. Most of my driving is highway as I live in the country.

 

Now is there anybody on here with a 09 Max Trailer package 6.2 with 373 gears? I think on Fullsizechevy.com there was a member who was looking at buying one but I don't know if he followed through or not. Just would be interesting to see what they are like. If I can find a 373 geared truck sitting when I go to buy ( crew or extended cab) that is what I want to drive.

 

The dealers around here are saying December or January before any 2010's show up, so for now I am being proactive.

I have a 2009 Sierra Denali with the 6.2 and take it from someone who owns several Corvette's, this thing is incredible.

 

I don't have a tune on it yet but I have no problems spinning the tires. Even with TC on it has impressive low end torque.

 

I can go from a Vette to this truck and not feel like I just climbed on to a turtles back like most trucks.

 

When I do get it tuned I am expecting a LOT more...like...playing with SRT8 Chargers.

Nice try, lol. I don't think a tuned 6.2 pickup would stand much of a chance against my car. I run well into the 12's....... like playing with C6 Corvettes..

 

Ribbing aside I did drive two 6.2 trucks before I bought the Dodge and didn't like them. Hence why I bought my Ram originally. The one had to have been a dud and that is all there is too it. It had no power and couldn't do much of anything. The salesman even drove it with me and was pretty baffled as to why it was so dead. I flipped the hood to make sure the emission sticker even said it had a 6.2 as I thought it had a 5.3 the way it carried on. The second one pulled a fair bit harder, especially up top, but down low was pretty soggy. I would think a tune would fix that. That and my potential truck would have 31" tires on 17's and 373 gears. Not the 342's and 20" tires like the ones I drove.

 

Here's hoping

[RyanbabZ71]

NHT pkg does include the 3.73's

 

Hopefully I will have my 2010 Crewcab soon and be able to give some insight into the 6.2

[hirevn]

I just got an 09 sierra denali and it seems to have some balls over my former 06 f150 modded and tuned truck. Now i havent really got on it much or towed with it yet as i am still in to break in.

I will be using it to tow my mid 9 sec bracket car most weekends (73 rs camaro) and my other toy (that likes to spank SRT8s & vets) is my paxton blown 08 stang .

Sorry, just had get a little ribbing in there too lol.

[uh6tdrvr]

hopefully you dont take this the wrong way but SRT8's arent THAT fast, at least stock. I work with a guy that has one and he can barely get away from my stock G8....at least 0-60....btw, the C6 covette has less hp than your car.

....back to the truck, motortrend did a truck comparo and i think they got 0-60 in 6.6 with a stock 6.2, 3.42's and the 6 speed. The best thin is its overall gear ratio's. 1st gear is low (4speed with 4.56's) . Comapritivly the toyota they tested it agains had 4.30's. and if you look at a toyota, imo there is no comparison. I will take my 5.3/6 speed combo over the yota.

I ordered a 2010 1500 4X4 last week with the Max Trailering Package and 3.73's.

Nope, I don't care much, I hold no loyalty. And btw, a C6 Vette weighs a good 1000 lbs less than my car does too......Kinda makes up for any power difference. And stock for stock there is no comparison...... I can't rib and add smilies on here I guess. There are dud SRT's out there as well. A buddy of mines 09 Superbee falls into that category. He runs what most near stock ones do with a custom tune, exhaust and intake. They aren't that sloooowwww of a car either, low 13's out of the box. Mine isn't stock btw..... But I am not here to discuss the pitfalls or whatever that every GM guy sees with my car. Heck no offense, but I don't want to talk to you guys about my Charger at all. Since I can see this is going to be an issue for some, I deleted the car from my signature. I just want to know opinions on the 6.2 trucks. Not everyone elses on why I shouldn't have bought an SRT8 Charger.......

 

Toyota's are ugly, no matter which direction you look at them from. I beat my buddy's 08 Tundra extended cab ( 5.7 of course) with my former 09 Ram at our local dragstrip. I don't see them as quick at all.

 

I like 373's in the Gm trucks, even with the 4.02 first in the tranny. Big tires kinda make the added gear reduction nice to have. That and really, with a .66 overdrive, I find the 3.42 cruise rpm on the low side for my liking. But hey, that's just me

 

Thanks for all the responses so far btw

Cool. So I am curious, and I know it's off topic. What does your Mustang run?

True and false, depends on what year C6 CoRvette you're talking about. From '05 to '07 it had the LS2 with 400 HP, from '08 to '10 it has the LS3 with 435 HP. If I recall the '09 SRT8 Charger 6.1L Hemi has 425 HP. Don't know what year Badass69's Charger is.

 

Either way, whether you're talking an LS2 or LS3 C6, it is still a lot faster than a SRT8 Charger, and if you have to actually hang a corner...fugitaboutit.

 

BTW, all the G8 engine options have less HP than the SRT8 Charger, and isn't there only like, 100 LBS difference in weight? I have heard the G8 GXP's are pretty quick for a 4 door sedan.
