5.7 Hemi V.s 5.3 Vortec

[Blue Bowtie]

I drove an '05 Dodge 2500 2WD single cab, stripped down work truck at work about a year ago. It was the new "hemi" and automatic, and was nothing to get excited about until you pulled it up to the gas pump. It's just another truck, and I think they may have finally fixed the front ends so the ball joints don't separate. Terrible ride, too, but it WAS a work truck after all. The '04 F-250 they had was a lot better ride, and moved a lot better with the 331" Triton (two-valve) and automatic.

If the chevy had the duramax diesel, then it would have blown the hemi out of the water. Those diesels are extremely FAST!!! Not the old clackers of the past.

2500 silverados are slow. My cousin has one and it slow cause it weighs alot. When my truck had the v6, i would beat him. Both stocks.

You mean the duramax would have blown apart trying to catch that Dodge

you know what is gonna spank the crap out of any stock pickup including the silvy ss and that one dodge rumbler truck with the rear spoiler thing? my truck... its a 73 chevy that is from the era that trucks werent anywhere near 6000 pounds and whatnot...i think if im not mistaken that it weighs in the 4000's somewhere... anyways, its got a 3 speed auto (th400) and a 12 bolt posi rearend that i cant seem to destroy no matter how hard i try. also, it is sitting in the garage awaiting the main attraction... a 350 bored .030 over with a 3.75inch stroke crank from a 400, which will make just slightly over 383 cubic inches, and will have 500lb/ft of torque and 450 horsepower, albeit only at the crank and with electric fans, which i cant afford because of the motor lol... but then again the fan clutch will help minimize power loss.

by the way, the horsepower specs given my manufacturers... are they regular at the crank style or are they at the wheels.... and do newer trucks all run electric fans nowdays?

im thinking this truck will be able to pull 13's in the quarter, prolly not much better due to the fact that it is a freakin truck lol...

also, whats the deal with that new 650lb/ft diesel from gm? did they just stick a bigger turbo on it or what lol?

With that weight, hp, and tq, that truck should do much better than 13s. My truck weighed in at 4400lbs, probably making roughly 400-410 to the wheels on motor and went 12.40. With that extra 150hp on the button, it does "slightly" better.

lol problem is that im running stock "rally" rims with some narrow-ass tires lol so ill probably have to upgrade lol

True True, I smoked the crap out of a Hemi with my silverado, Hemi trucks have gotten famous, but theyre not all that........well at least when they're being compared to chevy..........right?

I have the 05 VHO Silvy. (6.0). It's fast. For a stock truck. It's really fast. I can't say I've really really raced anything impressive, but no trucks have taken me off the line or down the road yet. (Again, I'm not out racing it all the time so... take that for what its worth) Almost 10,000 miles and not a problem yet. (knocking on head) Of course it might help that it's mostly my wifes truck (see name) and she takes AWESOME care of it.
I had a 2000 dodge dakota, (which i really liked) with the 5.9 magnum. I have to admit that motor was great in my book. 60,000 before I got rid of it and NOT A SINGLE PROBLEM. Great response from that motor too.
All in all i am a CHEVY guy, but to each his own.
AND TO ME MY CHEVY.... err... my wifes chevy.

Here are some vids of my truck, dunno if it helps much, but at the track were a few trucks, and the Hemi Ram, with equal mods, ran a consistant 15.7, while I was hitting 15.1 - 15.01 @ 91-92MPH.

I did a little research and Chevy by far has the most Horse power in it's class if you include the Vortec Max 6.0L
Now having said that.. Chevy does not do so good on torque. IN fact it is a little better than Toyota's tinny 4.7L. Now you have to consider weight as well. Chevy is the heaviest of all the trucks. I was really surprised. I figured Dodge would be the heavy one. Now Ford did not post there Curb weight, but I would suspect to be pretty close dodge, maybe a little more.
So depending on the road conditions and driver experience, I could see many different senarios happening.
BTW.. these are pulled from 2007 models from the manufacters website.
I love Chevy and I always will. but I will tell you, it is becoming harder and harder to choose. I am pretty envious of some of the other trucks, whether it be looks, power, torque and even options.
