Hooked on the 6.2, but wavering a bit

[SRJbb99]

Do you guys have dragstrip times to back up your 6.0's being faster?

 

My 2014 5.3 would walk my buddies CC Silverado SS pretty hard and beat my other buddies RCSB Max even worse.

 

Come on now, the SS is slower than the Max for one, and two, I don't think the 2007 and above VMax (not the older VMax 6.0 HO) came in regular cab (I can't find anything online that states that it came in regular cab. The brochures I find for 2007-2009 show it as not available).

Yeah, no max package for the RC models. Never been anything larger than the 5.3's in those. And depending on 2wd or AWD SS it shouldn't be much slower if any vs a Max. It's basically identical.. Either way it's prolly what and what with that of the new Gen V 5.3L, imo. I wouldn't bet on either in a race. I remember killing an SS though a few years ago with my 02 F150 Harley Davidson. I mean it was not even close. I even wondered if he had mashed the pedal, LOL. And mine was stock as well(albeit stock SC 345hp). That power under the curve from the SC is where its at and that's what makes a Gen V engine so great. They make so much more power thru the power band vs the gen IV.

Yeah a GMT900 Max isn't faster than a GMT800 version either. The L76 doesn't do any better than the LQ9..... in fact with the rectangular port heads it's worse honestly at anywhere below redline.

 

Like said above, guys don't get the power throughout the range on the Gen V.. they make awesome low and midrange power plus scream up too. It's like having your cake and eating it too!

I would like to mention when the 2500's came out(2008ish I think) with the 6spd behind the 6.0, it was night and day difference. When tuned they were a beast. I don't think the 6.0 ever saw this trans in the 1500 did it?? I remember a Vmax guy got his feelings hurt by a HD with that combo. And both were tuned. Always wished my old SS TB had the 6spd. Hated the 4spd crap!

2009 and it's a rare beast to find. That was the only year GM stuck the 6L80E( not the 6L90E like the HD's had but ratio wise its the same trans) behind the L76 and paired it with 3.73 gears. I hated those HD's lol.... had an 09 with 3.73's and yeah wound right out it moved okay but anything below about 4500 rpm it was a total dog. Cathedral port heads do so much better in a pickup truck than the rectangular ports. I wish I had the 8 speed my 15 has behind the LQ4 in my old 1500HD... would be a lot of fun.

That is a rare one! I test drove a 2009 2500hd single cab 6.0/6spd and she moved. I think it had a 3.73 gear and I was very impressed.

I had the 6.0l/6spd combo in my old 09 GMC 1500 Sierra AT and did like it, even better after I added a Diablew tune to it. I honestly don't think it would stand a chance against my current 15 Sierra with the 6.2l even with my 3.23 gears. Test driving 2 different 15s with the 6.2l and then getting into my 09 to drive home from the dealer really opened my eyes. The 6.2 is just a beast.

I don't have the 6.2, running the 5.3 here, but I can tell you, gears play a big role.

 

My 2011 with the 5.3 had 3:42's. Now I am running my 2015 5.3 with the max tow package which has the 3:73's in it. Combine the better gearing with the newer more powerful engine, and even this thing is a powerful beast. The 6.2 with 3:73's would be the ultimate.

My son has a 2006 cc 4x4 with the 6.0 with a tune and cold air intake. Took it to our local dragstrip and ran 14.7 @ 92 mph. There was a 2014 5.3 cc 4x4 there with a tune and he was running low 15's @ around 90 mph. He said on e-85 he could run mid 14's@ around 95 mph. My bone stock 2015 cc 4x4 has ran 13.7's 3 times hitting the speed limiter 60' from the finish line.

Gears do indeed! Yes I can attest to that combo being damn fun! lol
