Horsepower arguments

[Annhl8rX]

That 5.7 is a good motor, but it also has 25 more cubes and hemi heads are the best flowing design over all.
 
The Nissan 5.6 is also somewhat larger and is an overhead cam, but I don't have much experience on them.
 
I think both might be better compared to 6.2.
 
If you want to tune it, then go ahead and have some fun. [emoji4]

That’s a good point. I suppose I was making a similar unfair argument to the one I was trying to avoid.

Since you point it out, it brought up a question for me, though. Why is the smaller 5.3 the prevalent motor in the GM trucks? The 5.7 was the larger motor offered in the Dodge/Ram trucks, and was chosen so much more than the smaller V8 that they stopped making the other one. Why do more people choose the smaller motor in the GM trucks? Less emphasis on performance from the manufacturer? Do they have a bigger charge for upgrading to the 6.2?

The 5.3 is pretty much the standard motor across the 1500 series. It's all about the corporate fuel mileage ratings.

The 6.2 is the optional engine and does have a pretty big up charge. Around $2500 extra.

The 6.2L option was $2,750 I think (CAD) when I bought my 6.2L. My previous trucks were 5.3L's but I had 350's over the 305's in the 90's. They talked me into a 5.3L when I wanted a 6.2L in 2010 so I would not stand for it on my 2015. You get HP upgrades comparable to bolt-on's and a mild street cam for just over 2k. To get a 5.3L to make the same power as a 6.2L, you are voiding your warranty and you will probably spend more than 2K on your upgrades. To me anyway, the jump to the 6.2L is the cheapest most reliable HP gains you can get in these trucks. If you are a horsepower junkie or like to mod your vehicles, it really is a no-brainer to make the jump (if you are in the market for a SLT/LTZ).

That’s a little misleading. Back in 2014 when I bought mine I got the Texas edition package for 27K @ a 12K discount. It had E-85 ready option. Using E 85 got me within 40 HP of the 6.2. With the package I bought to get leather seats, Bose, and the 6.2 would have cost many thousands more. To reach 6.2 HP was a matter of a tune and a few other mods. The many years of car buying I always when with bang for the buck. Hopefully someday GM will offer the 6.2 in all models just like the competitors.

Comparing cars to trucks is kind of ridiculous to me, so I’ll keep stick to evaluating things with beds for now.

What do you think has a larger cargo volume. A 70 Caddy Eldorado trunk or the 5 foot box or the Crew Cab.  

 

The tread is horsepower. That's what's being compared.

I'll bet it's close and the Eldo has more leg room 

 

Annhl8rX  said he is getting a tune. That won't cost $2,750 (CAD) I'm thinking.

 

That 6.2 can push a $40K truck over $50K with the special packages that usually come with it.

 

10SierrA.T.  If that 6.2 is what you wanted then, it's all good.

That's a fact.

 

Picture this:  1970 black on black Eldorado cruising I-90 at an easy 160 mph.

 

 

140, if you were LUCKY and that's in the redline.  The thing didn't have enough gear to get it to 160.

Ok. But that wasn't really the point.

Yeah, I hear you it should even be available in WT if you want it bad enough. That's why I said if you're in the market for an LTZ or SLT it is an easy decision. A TVS2300 on a modest boost level on a L83 would put you around 450bhp if your lucky, cost you $7k usd or so installed, and void your warranty. If though you were already going with a loaded truck, the $2k is pennies for warrantied 65hp jump (not considering E85 here). By all means, if you are looking at a SLE/LT project truck 5.3L with an MSRP of $40k, the SLT/LTZ 6.2L at $55k would be a stupid choice as you could easily exceed those power levels with your extra $15k. 

 

Either way, these rolling computers are becoming less friendly to the horsepower junkies. Yes, we can make more power with this direct injection and timing technology but GM seems determined to lock these modules up tighter than Fort Knox. I don't think the LT family will ever be as loved as the LS and 4L60/80 trans series as far as hot-rodding is concerned which is why I wont be supercharging my LT truck like I had planned, I will continue my C6Z hunt instead and redo my 1998 as I have time. There just is no aftermarket support for these new trucks, especially in Canada I am 16hrs away from a reputable tuner.

Seems to be just intakes and exhaust. Could be the direct injection heads.
