Just read about speculation on the new 2011 GM HD's, looking at a 7.0 liter Direct Injection gas engine of around 450-475 hp & about same amount of torque...bring it on!!
New Dodge 6.4 Hemi around 450 HP & Torque ratings
New Ford 6.2 400 Hp & 420 lb/ft torque, RIP the 6.8 V10 in the F250/F350
they've spent so much time & energy on cranking up the diesel's power ratings over the last few years (and bringing up the addl cost to around $10k) it's about time they applied new technologies to their gas engines in the HD lines..
I can't see these high hp gassers lasting like a diesel, and they still can't produce the torque needed for heavy hauling. I wonder what the mpg ratings are. JMHO!!

It is interesting, but I would be more excited if they could focus their attention on improving gasser mpgs. 300 to 350 hp is enough for me, lets get pickup gasser mpgs up to 25 mpg highway. Now THAT would be something!
I agree, they could all do better in the mileage department. Personally, I doubt if I will get another gas after having had the diesels, but I do believe that the HP/Torque outputs on the newer diesels are sufficient for the truck ratings. I know some will always want more anyway, but the other side of the coin is that there are many other vehicle selections still to be had for towing/hauling heavier loads. I believe that there are alot of folks who could or would use a gasser if they were available with more HP/Torque, rather than pay the much larger expense of the diesel purchase. I had changed to all diesels years ago, paying the extra, simply because the fuel mileage was and still is 50% higher than the same truck with gas. Even though the fuel and engine cost more, it is still a money saver in the long run, not to mention the fact that the diesel, even heavily loaded, runs as if the truck were empty, while the gas with the same load needed another truck to push it out of it's own way. It will be interesting to see where these new engines shake out in the market as a whole.
They have been working on the gas engines for years.
Do you remember a 351 engine with over 250 HP? Now the slightly larger 5.4L has been at 300 HP since 2004.
The V 10 was only about 275 HP when they first started putting it into motorhomes in 1998. By changing to 3 valves per cylinder, they significantly increased the HP.
My 3.5 L V6 2007 Edge has 262 HP. That was unheard of power for a larger V8 found in the 65 Mustang, and it gets better mileage than the Mustang of old. Now they have a supercharged direct injection 3.5 L engine in the Taurus that is 360 HP and tons of power. That is more than my 225 HP 1997 460" 7.5L V8 was rated at from the factory.
Gassers and rattlers both... My '95 Dodge Cummins had an exhilarating 160hp and 400ft/lbs of torque with a 2500rpm limit meaning .69 O/D leaving 276 ft/lbs at the tail shaft to tow with. On up to 2003 when my '03 SO Cummins wheezed out 250hp and 460ft/lbs through .69 O/D for 317ft/lbs at the tail shaft. It's no wonder my current direct and multiplied 375ft/lbs tows faster up the hills than my previous higher torque through overdrive gear ratios reduce to lower torque. I have plenty of power now and no issues. Looking forward to even more usable power!

You'd better own a gas station, or know someone that does. , and you don't get those numbers running low compression, so be ready to pay for premium fuel too.

Exactly. I considered a diesel for my next truck until I saw the $6000 premium on the sticker compared to a $600 jump on a V10. I'll pass. $6,000 is a lot of gas when you are only paying a few cents less or even up.
Diesels are getting more and more expensive and the emissions equipment is really dragging down the mileage. I think as gas motors continue to improve they may become more desirable because of this. I have not heard of a 7.0L GM motor for a truck but I guess time will tell, I have my doubts a 7.0L small block GM V8 would be durable enough for a truck. How thin are the cylinder walls on the 7.0L dry sump Z06 Corvette motor?
