Can I beat a Hemi Ram?
 

I have an 03 Sierra single cab, step side with the 4.8Liter. What would it take to make it as fast or faster than a Hemi ram? Haven't raced one so don't know what the comparison is like but I'm sure I couldn'ttake one right now. Think with the ECU reprogram I could?

RE: Can I beat a Hemi Ram?
 

nah...need more cubic inches

RE: Can I beat a Hemi Ram?
 

Not with the program alone, but a few other mods as well and you should be good to go. (intake and exhaust)

RE: Can I beat a Hemi Ram?
 

Cool. I plan to get the ECU reprogrammed as soon as I can sell my Xbox 360. I'm gonna get one of those throttle body spacers too. Already got exaust and I did the free intake mod with K&N which helped a lot.

RE: Can I beat a Hemi Ram?
 

i got a throttle body spacer and injector spacer from cfm-tech. its made a huge improvment for only $120.

RE: Can I beat a Hemi Ram?
 

I dont know about the throttle body spacer. I have heard that they are not worth the money. Just a little gain of HP with a lot of money spent!!!

RE: Can I beat a Hemi Ram?
 

That's what everyone I've talked to locally said. But these guys all seem to agree that spending $50-60 on the trans-dapt tbs is a good deal.

RE: Can I beat a Hemi Ram?
 

My buddy has an old Ford with a 351 cleveland which we built to blow the doors off of the new Hemi Rams. It took quite a bit of mods but we did it. Your best bet (for money vs. power) is a light shot of Nitrous Oxide. Otherwise you need a list of mods for 4.8 or 5.3. A 6.0 will take the Hemi with exhaust, headers, intake, TBS, and a tune of some kind. A 5.3 will need more I'm sure. A good test is to do your mods then try to keep pace with a 4.6 Mustang (thats what we did). A stock 4.6 mustang will take a stock Hemi in a drag. Pace the stang = beat the Hemi.

RE: Can I beat a Hemi Ram?
 

the trans dapt is TBS is definately worth it. I gained 1 full second, and increased milage. Also my truck ran all over hemi's after just the intake and headers, they don't even try now.

RE: Can I beat a Hemi Ram?
 

I'd love to see your truck on the dyno Smoke. I can't get the Hemi Rams yet, but 99 - 2000 5.3 are only 270hp. Yours is 295 stock I think. But 72charger has a lighter truck but only 270hp himself. He might need more mods then that. What are the Hemi's rated at anyway?

RE: Can I beat a Hemi Ram?
 

i think u can stay at the bumper of a hemi ram..the way ur truck is now......cause all my truck has is a small cam, headers ,and flowmasters.......with 3:42 gears and 33's and i eat hemi rams all day long with no prob...ohh..yeah and a stock 06 2500 hd with the 6.0 and 4:10 gears all stock has no prob..beatin them either

RE: Can I beat a Hemi Ram?
 

345 hp on the new dodge with the hemi, 0-60 7.9 sec, quarter mile in 16 at 85.9. As opposed to 5.3 slverado 0-60 8.5, quarter at 16.5 @85.9. Also the Hemi is 200 lbs heavier. This is all stock info from consumer reports. Also notice the silverado is gaining after it gets past the torque management crap, they have the same quarter mile speed.
I also would like to see my truck dynoed, but after the tune.

RE: Can I beat a Hemi Ram?
 

Hhmm. Wonder what they run on the 1/8 mile stock. I know my truck was ran a best of 10.61 in the 1/8 mile with the only mod being a drop in K&N factory air filter replacement. I think with my mods and a tune I should be running a real low 10. We don't have a 1/4 mile track close by. I think the closest is in Panama City. I ain't driving that far.

RE: Can I beat a Hemi Ram?
 

I also think my truck is MUCH lighter than most Rams. I think that helps me a lot! My dad has a full size Sierra with the 5.3 and I've driven it quite a bit. It has a lot more torque than my truck but it is a much heavier than my truck. Most Hemi Rams I see around here are full size. Guess that gives me the advantage.;)

RE: Can I beat a Hemi Ram?
 

Yeah your truck is much lighter especially being a stepside (fiberglass bed). I think with a little more you will be good to go.

RE: Can I beat a Hemi Ram?
 

my buddy has a hemi and I wanted to race him but after we went for a drive one day he said "no way!!!!" his is also stock though.

RE: Can I beat a Hemi Ram?
 

I'm not sure I understand what you mean 78chev....

RE: Can I beat a Hemi Ram?
 

i think the buddy with the ram saw how quick 78chev's truck is and decided not to embarass himself by racing... my buddies with fords do the same thing... talk a big game til they see my truck in action

RE: Can I beat a Hemi Ram?
 

With only half a second difference, just take a laxative ([:@]) the night before the track and shed some weight.

RE: Can I beat a Hemi Ram?
 

ROFL!:D

RE: Can I beat a Hemi Ram?
 

WELL MY CO-WORKER HAS A 2003 4.8 SIERRA 2 DOOR AND SMOKES DA CRAP OUT OF A DODGE HEMI, WELL AT LEAST TAKES IT BY A TRUCK. ALL HE HAS DONE TO HIS TRUCK IS HIS REAR GEARS TO 3:73 WHICH MAKES A BIG DIFFERENCE, GIBSON HEADERS AND CAT BACK EXHAUST, K&N INTAKE, AND THE SUPERCHIPS PROGRAMER. I HONESTLY DIDN'T FILL A BIG GAIN WHEN I PUT THAT SUPERCHIPS PROGRAMER ON MY 97 SIERRA, BUT WHEN I CHANGED MY REAR.....WOW, BIG DIFFERENCE

RE: Can I beat a Hemi Ram?
 

gears are the best way to grab that power and put it to the pavement. i want to drop some 373s into mine:D

RE: Can I beat a Hemi Ram?
 

Anyone think it would be worth swapping gears on a 4X4? Double the cost.

RE: Can I beat a Hemi Ram?
 

I wouldn't. Unless you just like spending money

RE: Can I beat a Hemi Ram?
 

Yeah but it would be sweet! For that money I could drop quite a few mods Im sure. Ever see the CO2 cooling systems?

RE: Can I beat a Hemi Ram?
 

You can also add the mass airflow. summit racing has them.

RE: Can I beat a Hemi Ram?
 

changing the gears will get you faster torque. i plan on doing it to mine. i have a gmc sierra '07.

RE: Can I beat a Hemi Ram?
 

If you have the money, change the gears. You will notice a big difference

RE: Can I beat a Hemi Ram?
 

This may sound stupid, but are the 3.73 gears standard on a 05 Crewcab z71?

RE: Can I beat a Hemi Ram?
 

they were stock on my 99 z71, so probly

RE: Can I beat a Hemi Ram?
 

No, there were 3 options listed. 3.42, 3.73, 4.10. Although when I bought my truck I was told only 3.42 and 4.10 were available even though 3.73 was listed as an option.

RE: Can I beat a Hemi Ram?
 

I got a quote from the local 4 Wheel Parts to put in 3.73 gears ....$1456.00 installed.

GACK!!

RE: Can I beat a Hemi Ram?
 

Same price for 4.10s? Is that with a new limited slip or just gears?

RE: Can I beat a Hemi Ram?
 

He said the 4.10's would be more ..and it's just for gears.

RE: Can I beat a Hemi Ram?
 

Manthat sux! If I'm gonna spend that kind of cash for performance I'm getting a cam swap or something that'll actually make a big difference.

RE: Can I beat a Hemi Ram?
 

1500 dollars for the gear change??? Somebody israping somebody. Don't be scared to put them in yourself. Its not that hard of task. the gears are in between 300-500 daollars depending on the brand and the size of the rear so your really paying for the labor. You might as well buy a cam kit and and spend the extra money for more horsepower. But on my old 88 it don't take much to wake it up so its a lil different for you ls1 and ls2 guys. Jealous by the way. thinking bout a swap.

RE: Can I beat a Hemi Ram?
 

What would be the easiest way to tell which gears I have. I called my self looking through all the documentation, but I came up with nothing.

RE: Can I beat a Hemi Ram?
 

Need some more info on your truck year motor body drive type ect.

RE: Can I beat a Hemi Ram?
 

it is a 05 ChevyLT Z-71 crewcab 5.3

RE: Can I beat a Hemi Ram?
 

Thats the same truck smoke20 has and i have the ext. cab same thing I would say its got the 3:42 in it but i could be wrong you have to get the vin# to a chevy dealer and they can tell you.
