I was thinking earlier today about a truck pull... and from that point i started to wonder who would win between two identically equipped F-150's. The only difference between them would be the motor. If one truck were to be equipped with a 300 6 and the other were to have a 302. I was just wondering what you guys (and girls) thought. So please respond to my first post and give me some of your ideas


p.s. say they were both automatic simply to take away from the human factor involved with a clutch. And also for simplicity's sake say they somehow managed to clone the same driver so as to produce the smallest amount of human error possible. And i apologize for the long post but i just wanted to get my thoughts out there

 

Neither one, the sled would be to heavy to move?



Trick question?

 

In other words,

You're saying 300 vs 302 with everything else as the same.

I'd say 302. Many may disagree...but the reason I pick the 302 is because in a pull like that you need traction and the 300 has more low end torque making it easier to break traction and be pulled instead of pull. The 302 is going to be easier to manage when trying to keep traction and not break the rear tires free. Once you break the rear tires free and they spin, you loose your vehicular traction and are more susceptable to being pulled backwards if the other guy has more traction.

But...when you really want to compair their power levels...just look at a dyno graph of their power output.

It can be described as the 300 having the most torque down low at 2000 rpm. The tq will be high, in the 150-200ft-lb area at about 1000-1500. Reaches about 260 by 2000 rpm and doesn't drop below 200 til about 3200 rpm. Then the tq drops off and you start loosing power by about 3900. Between 4000-4800 it won't have much tq at all.


The 302 will be about 30-40+ ft-lbs less below 2000 rpm in the tq dept. It has considerably less low end tq. But the tq graph would be sharp where tq increases dramatically between 1800-3000 rpm. At 3000 rpm it makes the most tq at about 270 ft-lbs. It'll carry over 220ft-lbs till about 4800 rpm. Then by 4800-5500 it has very little tq...200 or less. However, the 302 definitely has more top end RPM power than the 300.

You put the two in a race...the 302 will beat it...even with a heavier truck. The 300 accerates slowly because it only makes 160hp and has a narrow RPM band of power. The 302 will easily out run it because of it's extra 45 horsepower. But the 351 will beat both of them by far and is definitely more powerful. It's pretty easy to notice...the 351 has the low end tq the 302 lacks...and pulls hard when accelerating up to about 4500 rpm. My truck does a pretty good 0-60 time even with a 170k mi 351.

TaDa.

 

Ok, I guess, but you don't think that it would go farther than the 302? I mean the 300 may break traction after a while, but the 302 is just going to bog down eventually as well, I have the 302 and I would still put my money on the 300-6.

Good thread though!

 

what about a 351 and a 300.....

That is a whole nother topic...


What do you mean by "go farther"....once traction is broken you're likely to just be pulled backwards...by then it's all over as long as the 302 vehicle maintains that advantage (IE driver ability). The 302 wouldn't bog down...in a manual tranny situation that would be arguable but not in an automatic.

The lack of low end tq on a 302 is much less evident with an automatic tranny behind it because of slippage. The manual tranny can force the 302 to work at lower RPMs if the driver puts it there...where the lack of low end is extremely evident.


This debate could go on and on forever....lol. It's really subjective since we're talking pulling eachother instead of just simply compairing the engine's power output.

Really, we're all just talking hypothetically and in theory....

 

Well yes, obviously, I meant that because of its torque, that it would go farther before it broke traction, than the 302 would before it bogs down.

As far as the difference between trannys, why does the manual tranny bog down faster than the automatic? mine is a manual and I know it would bog down before it lost traction.

 

I have pulled with a 300-6 ,c6 in a 78 f150 w/411 rears and it dose move the sled.

I love truck tug-o-wars. Years ago a couple of friends and I would host an annual tug-o-war on farmland just above the top of NJ, in NY State. There were two rules. You had to have a class-IV hitch thus providing a 2" box receiver for the tug-o-war chains. The second rule was pump gas only. We had some really weird entries over the years too... one guy used an old buick station wagon with off-road tires on a truck axle out back. He did pretty good for what it was.

Anyway, in a tug-o-war the only thing that matters is traction - if you have more traction than your competitor, you will win. Even if you're driving an F150 with an I300 and the other guy has a 500cid, supercharged monster.

I generally won these events, for two reasons. First, the truck I used was radically lifted, therefore my hitch was above your waist. They'd pull me at a downward angle, thus giving me more traction and them less traction. Second, I'd stand on the brakes while the starter pistol fired, and keep standing on them until my competitor started to spin his tires. Then I'l romp the throttle and pull forward. Once they spin their tires, that's it.

A lot of people cried "foul" but the rules were "pump gas" and "class 4 box hitch" and I met both requirements .

Plus, it really wasn't about winning, but more to hang out and drink/eat/socalize with guys/gals/kids who like trucks.
