Yes it is BUT the far bigger differences have to do with how each engine is designed and implemented rather than the actual cylinder configuration.

I'd guess that Ford went to the V8 for packaging (shorter) and marketing consistency with the prior engines.

Good points, and I agree with them all. The last thing I would do is attempt to haul over the limit. it's not worth the liability risk.

If the semis are inline 6's, it seems to me that there's a reason for that.

Now I need to find a 1 ton, or even better, a 3/4 ton that can pull a 353 Formula with fuel and beer legally. Suggestions?

yes big rigs are I6 and twice the size with alot more gears, if you drive 55 then buy a dodge if you use the truck every day and want to run the left lane buy a v8 they run faster better.

I have a 2006 Dodge quad cab dually for sale. 68,000 miles. G56 6 speed manual. Motor is bone stock except for True Flow air filter system and Fluidampr. PM me for more info.

BTW Ford has the rights to the Powerstroke name but I have a sneaking suspicion that most will call it the Scorpion. Much cooler name and the 6.0 and 6.4 folks are probably anxious to put the Powerstroke behind them and move on with this promising new motor...

It's too bad a manual will not be offered. My 1st and 2nd gears are 5.98 and 3.96 which is what you need to get a heavy load moving plus not having to use a gas-guzzling 4.88 like the F350s and F450s have to use for their auto trannies. My gear is the 3.73 and is perfect for the 6 speed Getrag manual.

Again, congrats to Ford for 1) going in-house with the new motor and 2) having the cojones to build a clean sheet design.

Depends on the powertrain. My truck will run 80 all day but the rpms would be well over 2500 which sucks down the diesel.

A 2500 with the automatic and 3.42 gears would be a much better choice. That truck would run 75 at 1900rpms. Cummins motors are not big revvers so you need the right gearing in the trans and the rear end to make it run without burning lots of fuel.

I hadn't thought about a manual. First, first I've got see if I can close the deal on the 353.

Hey best of luck with that. It's good to see people buying boats again!

My truck is still for sale. I have not had one issue with it in almost 70,000 miles. The Cummins is finally broken in and the mileage has increased. I'm seeing 22-24mpg now. The hitch is rated for 12,500lbs so it should tow that rig with no problems.

All 2008+ Diesels get poor mileage. That is because of the EPA regulations.

My 6.4 has been 100% flawless and gets 15 MPG city. Which isn't great nor is it terrible.
I does pull my boat very well though!!!!!!

That's true the new regs have hurt mileage but Dodge at least is working on solutions for their 2nd gen 6.7 due out in 2012. The Cummins doesn't need urea either.

That's good mileage for a PStroke. It's a good thing you don't have the F450 with the 4.88 which gets 12-13 hwy and 7-8mpg towing. That really sucks.
