Aww, now beggers can't be choosers. Here's yours.

 

I'm used to the cheap stuff anyway.

 

This is better than the 460 vs 5.4 thread that got closed!...........Throw me one of those beers!

 

Actually it's not that simple. Those are peak Hp and torque ratings. The two engines have completely different torque curves and engine operating speeds. You can make an acceleration contest with a scenario where the V10 wins, or a scenario where the 7.3L wins.

Pretend you can measure torque, engine speed, and elapsed time during an acceleration run. You can use this data to find out at which engine speeds you make good torque, and how much time you spend at various engine speeds. If you want to accelerate quicker then you must increase the area under the torque curve at the engine speeds where you spend most of the time while accelerating. In other words, maximize the time that you make high torque. That is exactly what a diesel engine does, and it can do it all day without issues and with greater efficiency than a spark ignition engine. As you add weight to each truck the 7.3L will continue to close the gap until eventually it out accelerates the V10.

Not everybody wants a diesel. They drive different, clatter, sometimes smell, and have a maintenance schedule that most people won't adhere to. The V10 is a good marketing move by Ford because it gives trucks owners a powerful engine suitable for a 3/4 ton truck, but with driveability more like a car then a tractor.

 

Here you go!

I'll leave the tap open, everybody help themselves, and enjoy the show.

 

Torque is multiplied by gearing.

The 7.3 came with 3.73 gears stock.
The 6.8 came with 4.30 gears stock.

505*3.73 = 1883
457*4.30 = 1965

The V10 has more rear wheel torque than the stock 7.3 truck. Obviously you can change things, gearing, programmer, etc., and ad nauseum; however, to blanketely say one will out accelerate may not be the case.

By the way, pickuptrucks.com had a comparison with the 6.4L diesel and 6.8L gas and found them to be very close, with the 6.8L continuing to accelerate when the diesel had maxed out...so, again, stock trucks, you'd be hard pressed to make a winner out of either, or as easily I guess you could make a winner out of either.

 

My 99 7.3 PSD gets 20MPG @ 70MPH. This was the average on a roundtrip from Denver to Baltimore. Going from Denver (~5400' altitude) up to Keystone or Breckenridge (~11,000' altitude) I would average 18MPG+. I do plan to drive the wheels off it. My ex-gf had a gasser and she liked it just fine, but whenever we towed her 20' horse trailer with a couple horses, we always took my diesel.

Gas or diesel, it depends on what you'll really use it for, how much cash you have, and just simple preference. Maybe I could have gotten a V10 that would do just as good, but I prefer the diesel. My mechanic buddy (25+ years Ford tech) recommended the 7.3 to me as well. Some things are crazy expensive, but I know she'll last.

If you're looking to buy a truck, why not just go out & drive a couple different ones and see what you like?

 

If you apply same year model motors it comes out a little different.

2002 PSD, 525 x 3.73 = 1958
2002 V10, 425 x 3.73 = 1585

If you change both to 4:10 you get 2152 and 1742

 

The v10 is worth more than you give it credit for.
I know of a guy with a v10 f550 with 4.88s. It is a tow truck and he has pulled a f650 with a load on the bed.
the f650 came out to 26000 plus the tow truck made it 33,000 combined.
He hit a 6% grade and held it WOT.
He started the hill at 55 and hit the top at 57.
the v10 is a great light AND medium duty truck motor.

 

But unfortunately, that's the problem. You've only owned your 7.3 for a year. Wait for it.

 

So why does my 02 have 3.73s, stock.

 

Funny, that's the exact type of truck I got...

 

I need another beer...........This is great stuff!

 

It's a silly debate really. It boils down to what do you want? V-10s are fine engines, and the 7.3's are good too. Don't know enough about the 6.0's or the 6.4's, can't comment specifically about them. Both have their little quirks, so, it boils down to what do you want? When you get down to it, the only opinion that matters is your own. You've got nothing to prove to anybody. Just get the truck you want, and be happy with it.

 

Yup, get the engine that YOU want. Here's a helpful guide!

V10 = Drinks like a alky, puts out like a *****.

7.3 = Smelly, loud, but dependable. Just like your favorite Uncle.

6.0 = Buy this if you hate your bank account.

6.4 = A motor to twirl eco-queers' *** hairs. Pull trailers, save the environment, and yank the cab if anything breaks!
