u happen to kno the hp and torque for an efi 300,i kno it aint nothing compared to the 5.3,but i have pulled a 5.3 with my 300 about a year ago, all those ponies made his tires spin if u kno what ur doin and what your in for that can help a lot in pulling off

 

The EFI 4.9 had around 160hp and 265tq. I don't remember at what RPMs though.

I agree, knowing what you're doing is half of winning. It's like the saying, "straight roads are for fast cars, curved roads are for fast drivers."

You're just going to need a lot MORE experience to beat a truck that has over twice the horsepower and a lot more torque. Doable, but you need to be realistic.

 

I did give wrong advice, mentioning the clutch. To win this race, he should rev to 3500 in neutral, then drop the shifter into 1 or L. This will help beat the Chev.

If you follow all the posts and advice given here, I think you will understand why I think it's so important to give winning advice here.

 

just look at it this way.if u dont really like the guy,tell him to drain some oil out of the engine KABOOM lol.i think its a safe bet his engine isnt as tough as your 300,or any other gasser v8 out there

 

Your butchering of the english language aside, i think you should define the word "beat". Some people seem to think that its a drag race, and others seem to think that its a tug (probably because they know the 300 is so much slower than a 5.3 that theyre assuming you couldnt possibly be stupid enough to race one seriously). I myself am mystified by the fact that you have not clarified already...

Truth be told though, youd probably lose either way.

Ive seen airflow data on the 5.3 head and its pretty good down low, no worse than a 300s head. So just because its peaking at 3000 rpm, doesnt mean it isnt matching or beating your mild 255 lb-ft at your precious 1400 rpm...

 

I agree on you being beat by the chevy drag racing, don't even try. And for the love of god don't take oil out of your engine, you don't have a briggs and straton, it's not hitting the crank and won't until you fill it about 2 quarts over full. Anyways, as for pulling, (hooking a chain between the 2 trucks) you could beat him easily. I bet I could beat him with a 50hp engine, why? It's in a tractor, why would a 5800 lb IH 460 out tug it? Traction, geared low... So as far as that goes, make sure your hitch is the same height as his or a little higher, once that's established you need to cheat somewhat, make a bar that goes from leaf spring to leaf spring and it will be about an inch from your rear axle bump stops, then take some rachet straps and strap from frame to axle until all movement is gone (solid rear suspension), this will get rid of your hop, maybe.... there is always axle wrap to be worried about, but the only way that can be fixed is ladder bars. After that, make sure your hitch is still at least even with his, then start adding weight wherever you can get it, on a 2wd peferably right over or in front of the rear axle. All and all the trick to bumper pulling is to keep the wheel hop out of the picture, that's when stuff breaks. You also have an auto if I'm correct, that makes it easier, power brake (no tires spinning) in 1st and as he starts to pull on you keep your brakes held and once he breaks traction you ease off the brake and into the gas and although I don't know what kind of surface you plan on doing this on, once he's spinning you get the advantage of starting with more traction. Also beware of him having a posi, a lot of newer trucks do, in that case it wouldn't be to fair. If you plan on doing this on cement, diffintently let him tug first, w/ you holding the brakes he'll most likely break something b4 you ever get to tug back if he gets a lot of traction.

 

yeah, be an *******, hold the brakes so he breaks his running gear, and then say you won because of your engines mighty torque, and proudly proclaim that chevies are pieces of crap because they installed a limited slip which gave the truck "too much traction" and caused something to break...nice work redneck cowboy....way to beat the system. quick question though. if you were to try and tug someone else like you, how long would it take before you both realized you dont have the ***** to win without trying to break the other truck? would you both sit there for 10 minutes holding the brakes and revving your engines, waiting for the other guy to go first? Whats the matter man? Your 300 cant take a pos chevy? come on now...those things are v8 screamers. you got that low end torque...you should be able to win without even breaking a sweat, right?

 

As grabasstic as these things are, you do have a chance in a pull off. However, if you have to ask if you have a chance you probably don't have the skill to pull it off. In a race you don't have a chance in hell.

Don't drain any fluids out of your truck. That is the single stupidist thing I've heard said in a long time.

The 5.3 is an OK engine, but it isn't a truck engine. It's a car engine that got installed in a truck. At the shop I used to work at we did $5k in mods to a 5.3 and it only put out 10 ft-lbs more torque than my 4.9 did, and it took the 5.3 2500 more rpm to do it. There was also a fairly quick drop on either side of the peak. In a pull off there is no way the Chevy will even get to its torque peak unless the tires are spinning. There are no more gas truck engines. Sigh.

 

Lol, well don't break his truck, I said wait till he breaks traction first, then his tires well heat up and he'll have less traction (on cement) as far as gravel, dirt and grass go, well that's a different story. But like I said, in these little contests as long as you have a decent motor (300 will do just fine) it's traction that counts.

I'd sit for about 10 seconds, then let er rip. I'm not the slightest bit scared of breaking my truck, I'm always looking for a reason for something bigger and better, but that's just me.

 

No matter what anyone eltse says on here, all it comes down to is gearing and traction. You could tow a tank with a Briggs & Stratton with the right setup. Put like a 10:1 rear end and some huge tires on your truck and youll tear his truck apart. But otherwise, you will probibly get smoked.

 

its all down to the setup?whata 6cyl witha 10:1 would pull a tank? LOL

 

Didn't they use a GM 6 cyl. in the old tanks?

 

they might have

 

Someone had to say it...I tried to give you more reputation points Harte but it won't let me!
