You mean you found one 7.3 that made it a million miles? WOW!! And one 6 leaker that made it 400k? I wonder how many headbolts, turbos, etc it went through. For the price of a long block 7.3 or 6.0, I could buy 3-4 long block V-10's.

Pappy, if traction is equal in the pull-a-thon, who wins, and why?

????. That's your solution? What is this going to do for you? Your going to powerbrake around 1600 rpms? If your 2000 rpms when you come off the brake your going to be spinning. I've tried. And its a task holding it back at that. My truck tries to crip forward.
Your looking at dumping all of the tq to the road at once. Traction will be broke just as soon as you let go of the brake. The best thing I've found is hold at 1500 and stomp at green.

And a 5-8psi boosted launch is CRAZY!

Oh, and the 7.3 w/ a million is origional motor. Just stock and well maintained by an X-Ford employee who runs campers across the country as his retirement job. And I believe he is over 1,200,000 miles now, or something like that.

That's the fella, I read he crossed the 1.2M mark, but still have the article from when he crossed 1M. And that 7.3 is still hauling 5th wheels across the country. The owner's proud, as he should be, if I get haft that out of my 6.0L PSD I'd be happy.

He prolly thing the 7.3l will last longer than the v10 because if he lives in a area like me 7.3s has a lot more miles on them.
I'm going to tell ya right now what a 6.8 is going to do if it hooks up to a disc. Its gonna spin. I've done seen itbwith my own eyes. Never mind adding the truck. But yes the v10 will pull it. Its just gonna spin. That is the advantage of low end tq. I'm rolling forward at idel or slightly above with your peak tq.

He really took me off the line but I caught up and passed him pretty quick.
His v10 has about 70,000 km's on it and it runs tired though. I've been asking a few people about those lately, they all seem to share the same opinion that the engine put out when it was new, but it just does not run like it used to. These are not all high mileage trucks either.
That brings up another topic - how does the truck run after 400,000 miles ? I know my old 7.3 idi had HUGE miles on it, and it still purred like brand new. Most gasoline engines I've personally been around with that kind of mileage were either barely running, or running not nearly as nice as my diesel.
To each their own.

I just raced buddy this morning and beat him pretty good with my 6.4

The only reason for any engine in the Modular family to be tired at such a low mileage is poor maintance.
If his truck has 70,000 kms and is tired than there is something more going on there.

I personally know of one V10 van well in excess of a million miles about 40 miles from me. I know of a 5.4 van and a 4.6 limo both over a million too.
