If you want gobs of low-end torque and don't care about revving it, swap in a 300. The 300 and 351 will out-pull the 30-anything all day long. The 300 will get better mileage than the 351 will too.

 

You mean if he wants a little less torque at a slightly lower rpm with less HP and less power overall......

I haven't seen a side-by-side dyno chart for the three motors before. That's interesting info, I stand corrected.

 

300s rule off idle compared to a 302. It creates the monster torque impression.

I just deleted a post that all but challenged the OP's sanity. Given what he wants, I think he should polish up his truck and drive it as is. Drive it with pride I might add.....

 

I like my 300. With a cam swap, it would be even better. I hate how it sounds though so I'm eventually going to pull it and put in something bigger. That's way down the line though.

 

I had a '95 F-150 with a stock 351W, E4OD, 3.55 gears and 33" tires. Definitely NOT geared for towing. I found it completely acceptable (although not at all exciting) moving a GCW of about 9,000 - 10,000 lbs (includes the truck weight). I've hauled the same load with an '02 PowerStroke and my '97 460. Both, although heavier trucks, would run away from the 351. Surprise, turbo-diesels and big-blocks make more power and torque than a small block! But of the three, I wish I still had the 351. It was all the power I ever needed and it had the lowest fuel cost of the three in normal driving.

 

Which don't mean squat unless you are driving from Houston to Beaumont every day of the year, and if that's a one-tank affair I doubt that it's accurate. I can get my 460 to get 15 mpg in that situation but it's not what I see driving it every day. Taking that number and saying, "My 460 gets 15 mpg" is not true.

 

You callin me out.. ****!

That is for real highway gas milage from that combo, I used to do a lot of highway driving and it consistently got high teens. Around town though it consistently got about 13mpg which is about as good as one can expect from a 5000lb vehicle. Real people here with real numbers.. no funny business.

 

OK, Paul, you win.

Now I will start another fight - most of the 300 hype is just that: hype. I've owned both the 300 and the 302 (and put >150K on each) and I liked the 302 better. The 300 is a tractor motor, it does pull better off idle, but after that, it's a wash, except that the 300 makes very unhappy noises anywhere north of 2500 RPM. However, neither one of them is fit to carry my 460s jock strap in the torque department.

 

i was waiting for someone to say this, wasnt gonna talk up the 300 like i usually do becuase i cant figure out what the OP wants, one moment its low end torque the next its high rpm cams....

 

i am in the same boat as you, i currently have my 92 4.9 and my 94 5.0 the 5.0 has 227,000 miles on it, the 4.9 has 120,000 so considerably less, but to keep this to an honest comparison i will use my grandpas old scrap hauling truck (which i drove.... alot) which also had a 4.9 but had a mazda 5 speed instead of e4ods like my trucks have. anyway using my grandpas truck means that the 5.0 has 227,000 miles and the 4.9 from my grandpas truck had 287,000 miles on it. both of these trucks got, and the 5.0 still gets, used hard, as in way overloaded from time to time pulling 10,000 pounds (about how much a load of scrap weighed without trailer) in the hilly backroads. the 5.0 AT FIRST did much better at towing than the 4.9 did, i should mention that the 5.0 has 3.55s and the 4.9 had 3.08s in the rearends. anyway like i said the 5.0 did much better at getting to speed and keeping speed... as long as you kept the rpms up, try to lug it in overdrive like you could with the 300 and it fell on its face. at first revving it up didnt seem to bad, but now flash forward to today, the 5.0 is so worn out it cant go faster than 68 mph when its floored, and the 4.9 is still hauling loads, as its now a farm truck for a good friend, the last load i hauled with the 4.9 was shortly after i hauled a load with the 5.0 and on the same route, the 4.9 was no doubt more wore out compared to before, but the 5.0 is much more wore out than the 5.0, and that is why i prefer the 4.9, it lasts longer and holds up noticeably better than the 5.0 does. about the only reason i keep the 5.0 anymore, is to see just now many miles it will go before it dies.

 

That's why I'm going to build a 460 or bigger when I get around to building an engine. It's got the off idle torque and the top end power to make you smile every time you drive it until you hit the gas pump.

 

Why not a simple 347 like was suggested earlier. Other than the increase in stroke, keep the rest as stock as possible. The Eagle kit is roughly $1,000 and you'd have (guessing here) 320-330lbs of torque?

I bet you you'd be very happy with that as a DD and occasional realistic-load towing.
