Anybody towing with a late model gasser?

You eagerly mentioned HP numbers, now lets hear those torque numbers.

If you had a motor which made 10,000 ft-lbs of torque but only 100 HP, any modern V6 would be able to out-tow it on hills or flats. The only difference is the 10,000ft-lb motor would be turning at a much slower RPM. HP is what matters. Torque is only relevant because that affects the RPMs peak HP occurs at, and how "flat" that HP curve is (which keeps more HP available more often).

BTW - most of my work trucks have been diesel, including an '08 Ram 6.7L. On the same grade (7%), with more weight behind my V10, the V10 will hold a higher top speed on that grade compared to the 6.7L could. Main difference was 4800 RPM vs 3200 RPM. The V10 could can pull more weight than than a 6.7L cab-chassis simply because it makes more HP, even though the 6.7L makes more torque, had a lower final drive ratio, and deeper gears in the transmission. The 6.7L was faster with a load up to about 25 MPH, at which point the V10 has the HP advantage. In the 2-years I drove that truck, it never made me want to trade my gasser for a diesel. In fact it left a bad taste for new diesels due to the numerous problems it had. It did make me wish I had more gears behind my motor, so I'm hoping to address that this summer:)
