They were also slower than just about anything ever made, and the only reason they came with the 300-6 is because they were cheap, and marginally better on fuel then a V8.
I personally knew someone with a UPS-Style Grumman aluminum body step-van with a 300-6. It could barely do 55 on a level road completely unloaded.

if they could barely do 55 i'm pretty sure they wouldnt have been in the trucks more than a year which they were. also ask him what gears it had i wonder why it would suck with the wrong gears (hint overrevved)

It all boils down to rotating weight/mass ...
SBF's simply do not have the rotating weight/mass it takes to make a tow motor ... However that is also what makes them fun on the street and fast at the strip!
They are quick revving.
The i6 has the rotating weight/mass, thus makes a good tow motor, but they are boring on the street and suck at the strip!
However, I have had the pleasure of a N/A i6 that put most sb's (all mfg's) to shame at the track ... But that was a long long time ago, things are different today with all the modern high tech electronics and crap.
-Enjoy

im not saying that it wasnt a economical motor in the terms of durability and and low operating cost i am saying that its not a fuel efficient motor i completely and totally agree that it is durable and cheaper to maintain. also i dont think the motor gets the credit it deserves in respect of what it can due if it was put in to machines listed above. all i want to know is if anyone has dynoed a factory motor to see if the numbers are accurate. also to Evan P go ahead and build that 351 and then we'll meet except i use my other grandpa's 400 big block backed by a 4 speed and kick the crap out of any 351 you can build for absolutely no cost to me. dont try and say your built 351 will out pull my grandpa's 400 as its built up the a** and regularly hauls tripple axle gooseneck trailers loaded with all sorts of crap with no problem. ohh did i mention it was a 78 f150 custom. just so you dont say that there is no way a 150 will handle that he built it using aftermarket parts with a 2 ton trucks weight rating

How did we get to a 400? I offer simple input that a larger motor is better for towing and that they are cheaper to make towing motors, and you come back not even defending the 300, but instead saying the 351 sucks compared to a 400. No S#!T a 400 is more powerful. If you don't have any facts to post and can't take honest opinions do us a favor and find another forum. Stop being a keyboard jockey. Your not impressing any of us here. Here's another bit of advice, don't go around saying you'll beat anyone's truck using a truck that does NOT belong to you...

Wow....Just..wow
My truck is a mundane, 300/5 speed/3.08 truck.
In short, it gets the job done and is reliable. Period.
I plan on doing some work to it, along with a gear change. But if you think, stock for stock, a 4.9l is gonna beat a 5.0/5.8.. Buddy, I want some of what you're smoking.
A 300 runs out of breath at the same rpm a 302 is just catching its breath to run. And a 351 simply combines both.
As for your "hauling"...My largest load was a 1976 dodge 1 ton dually gasser, on a 16' bed and I rolled across the scales at 11,360 gvw...that is GROSSLY over weight. Period.
Going up the hills, it would BARELY muster 30-45mph..In 2/3rdgear, fuel pedal flat on the floor.
The engine was made in the 1950's when the average speed limit on the interstate was 50-55, not 70 like today.
I honestly think you're a child with 0 idea of what hp/tq truly mean, and are trying to troll the hell out of us.

i never said the 4.9 will beat a 5.0/ 5.8. i take that back i have done side to side towing "experiments" with my grandpa and his 5.0 compared to my 4.9 with very simarly weighted loades and the 4.9 out pulled it by a long shot as for the 5.8 i dont know as for both of them having more hp and being faster on the street thats just obvious that the two would be faster than a six cylinder... i would hope
