Looking at a truck. opinions?

Only if you're planning on reving it past 4000 RPMs.

Sorry, but I just had to clear up a very common misconseption about how the SOHC is "more powerful" than the OHV. The only difference between the two 4L's is that the OHV revs to 4000 while the SOHC revs to 6000. The extra horsepower comes in that extra 2000 rpms. While that is useful when you're accelerating with the pedal on the floor, shifting at redline, that's not how most of us go around driving everyday, and is an especially bad idea when you have a trailer behind the truck. So in everyday driving and towing, there is no difference between the two 4L's.

It would essentially produce more power through out the powerband... It doesn't sit at the same power level through the RPM's and then magicly jump 20 more when the truck hits 4000.

Say at 2000 rpm the OHV would produce like 120hp or something... the SOHC would probably be producing 123hp because the band is slightly higher then that of the OHV.

heck i would have bought that trs truck in a heartbeat if I had known about it when I sold my f150. I didnt know about this site then.

 

[Mr99Ranger]

I'm going to probly buy it on sun. And I'm not gonna mod a thing till it needs it. Theres nothing like an original truck. Course theres nothin like a custom one either

 

[IlovemybroncII]

for the price i would have green one

You're missing the point. The formula for horse power is torque x rpm / 5252. The 5252 is a conversion factor necessary when dealing in standard units, it wouldn't be there if we were in the metric system.

The 4.0 OHV makes it's peak horsepower of 160 at about 4000 rpm. Working the formula backwards, it's making 210 lb-ft of torque (160 = 210 x 4000 /5252). Due to the airflow properties of the OHV's heads, intake, exhaust, and cam profile, the torque falls off badly after 4000 RPM, so even though the engine might be spinning faster (which, according to the formula has the effect of increasing HP) the torque is falling off so badly that the HP goes down.

The 4.0 SOHC, with its better flowing heads, intake, exhaust, and cam profile, keeps on producing good torque up to about 6000 RPM. So at its peak of 210 HP at 6000 RPM, it's making 184 ft-lbs of torque (210 = 184 x 6000 / 5252). At 4000 RPM, after which the 4.0 OHV is done for, the SOHC is making about the same torque as the OHV, resulting in the same HP at 4000. The difference is that it keeps making torque for another 2000 RPMs. Since HP is nothing but torque x RPM (with a constant conversion factor), it makes more peak HP simply because it can spin faster.

And I'm not saying they make exactly the same numbers 0 - 4000 RPM, just that they're close enough that you won't notice the difference until you have 'em floored past 4000 RPM.

Here is a quick sketch I made in paint to try to explain what I am saying. It's not perfectly accurate or to scale by any means. But it does kind of show the difference between the two engines:

Well I see what your saying I'm just talking about the entire band is going to be a few ponies higher on the SOHC.

Lol not like I would know anyways... I got a 3.0L only driven a 4.0L once... My 2.8L is definately more ballzy then the 3.0l but the 3.0L is really nice and tame for city/winter driving.

 

[Sevensecondsuv]

Yeah I hear you. Everybody talks about how great the 4.0L is, which may be true in a ranger, but the sheer mass of an explorer will bring one to it's knees. My explorer with a very healthy 4.0 was only slightly faster than my 2.3 ranger when it was stock.

nice truck mines an 04 with 99k on it and since i take care of it and do preventative maintenence, she looks and acts like a new truck! i thought mine was kinda high miles for an 04 when i got it, but as long as you take care of it, it will last a long time

 

[Mr99Ranger]

I went to look at the truck again, and when I drove it, the synchros seemed kinda, well, non functional. also seems the clutch slips a little. So I decided against this truck, unless I can get it for a rock bottom price, and have gone and driven this 2000 reg. cab 4.0 auto. It has an offroad package, and runs and shifts great. My 99 has the same motor and mileage, but mine's an ext. cab, and man does this thing feel sprightly compared to my truck. And 4.10 gears with trac-loc! I have seen very few reg. cab 4x4 4.0s with the offraod package. He said I could have it for $5,000 out the door. So I think this will, in face, be my new 2nd. truck.

[Mr99Ranger]

Oh, and I love the color.

 

[Original_Ranger84]

Regular cabs are something else. you can't beat the extra cab room of the ex cabs but the regular cab a sort of feel to it that you just don't get with the ex cab.

Gotta agree there. This thing drives almost like a sports car!
