Would appreciate some comments on the pros and cons of the two engines. I tow a Buick Rendevous and need some "oomph" to get me up the hills etc.

I have owned both. Currently driving the 8.1 chevy. Both are very strong engines. Can't say I prefer one over the other. I have a 31 ft A and pull a very heavy Bass boat or a Hummer 3 with no problem at all. Passes everything except a gas station.

Cant say bout the v-10 I have the 8.1. 56,000 miles about half towing, you can see my weight charts on my web site. 4.10 rear gears. non towing about 9.8. Towing my 37' TT at 55 about 7-8. No problems yet. Seems to pull up all the hills just fine.

I have an Excursion Limited V-10 and love it. I pull a Jayco 27BH with it, and it pulls it beautifully. Towing = 9.7mpg last trip. Non-towing = 13 mpg average.

Which Chevy engine?
The 6.0 has about 3/4 of the torque of the Ford 6.8, nearly the same maximum horsepower of the 2-valve V10, 20% less than the 3-valve V10. But the maximum power is delivered on a short high RPM peak, while the V10 has a broad (almost 2000 rpm) band where HP is within 5% of peak.
The GM 8.1 Vortec pretty well matches the 6.8 V10 on torque and horsepower from about 2000 rpm to 4000 rpm, but is just a little more peaky, and the ECM cuts off power more than 1000 rpm sooner.
Going up a hill, you need to be at maximum horsepower. You don't always have enough gears to match max horsepower rpm to the speed you could take the hill, if you could get that power. The broader powerband of the Ford makes it a little easier to get a match. But the Allison transmission matched to the 8.1 Vortec gives you more gear ratios to work with.
If you are trying to maintain a speed on the hills to match car traffic, you probably need more than a little more oomph. To match the power to weight of a even a modestly powered car like a 4 cylinder Civic or Accord, a 20,000 rig needs 500 to 600 hp. If you've got 340 hp to work with you are going to slow down. Swapping that out for 360 hp, you will hardly notice the difference.

Well.. First the 8.1L Vortec is a GM engine, While I don't have a lot of experience with truck engines I know GM car engines tend to last a while if cared for. FORD engines on the other hand seem to die younger for me.
The FORD V-10 is a "high rev" engine, the Vortec is a low-rev engine, (Produces more HP and Torque at lower RPM)
They have the SAME max torque ratings, only chevy does it at lower RPM
The ford has slightly higher HP (about 5% IIRC) but at much higher RPM.
The GM engine often has an ALLISON transmission bolted to the output end
And though we could argue which is the better engine till the cows come home.. ALLISON is, beyond a doubt, the best transmission.

"ALLISON is, beyond a doubt, the best transmission."
Camparing 5-speed (one of the Allison models) to 5-speed (Ford's newer TorqueFlight), why is the Allison better than Ford's 5-speed TorqueFlight with Tow/Haul mode?
I just returned from a 3700 mile trip to several states in the West traveling on various grades (some very steep) and at various altitudes.
The 305 HP V10 in my small Class C could "just about" keep up with anything on the road if I rev'd it. Sometimes 4400 rpm would be required ... but I usually tried to keep it at no more than 3500 rpm, having to slow up from the prevailing speed of other vehicles to go no higher than this rpm.

Workhorse is now owned by Navistar (International). I would imagine they will eventually dump GM as their primary engine supplier, utilizing their own engines as well others (Ford, etc.). GM will soon replace the 8.1 liter engine as it is old technology.

I drive a 24 seat shuttle buss for a living, my assigned bus is an 8.1 liter Chev, for most of the summer I had to drive a Ford with a v-10, in all categories, acceleration from a stop, pulling power, and transmission smoothness the Chevy beats the ford hands down, granted the fords are about the same in manitenance costs and a little better in fuel economy, but in this business your talking 7-8 miles to a gallon.
