That basically sums up what I was getting at, my uncle just dropped something like 10k$$$ on two newer Duramax diesel's just out of warranty. After all the crap he used to give me about owning a gas truck the last time I talked to him he swore up-and-down he is never going to own a diesel truck again... I have nothing against Diesel engines but in my opinion they need to pay for themselves to be worth it.

If they do come out with a 7.3L gasser (I highly doubt it) it would be a gas guzzler. It would get maybe 10-12mpg. So on that note I would be out even though a big block in these new super duty would be cool.

You're probably right, however, they've came a long way with these engines. They could use "variable displacement" technology to make that engine get better fuel mileage, and great torque. My son had a Chevy 1500 with a 5.4 that used that technology.

Before the manufacturers sort of forced us into buying diesel to tow heavy, I bought 2 new Chevy crew cab duallies with 6 speeds and the 8.1 back in 2002.
That was an awesome motor and would get about what the guys are saying the new 6.2 does MPG wise.
I would get 16 empty on the highways and 9 with a 12K GN horse trailer on it.

Yep- displacement on demand. Pushrods make that easier.

Its not without its faults though. I don't know the exact terminology, but they have had issues with the valvetrain on the mds motors.

I think there is a market for a gas truck that creeps closer to diesel capabilities. The 6.2 is a nice motor but the gap in ability and price between it and the 6.7 is pretty sizable. The F150 will have 5 motor options next year. I guess you could say the SD has 4 if you count the 6.8 and the detuned version of the 6.7, but they are chassis specific. Perhaps they'll do away with the 6.8 and broaden the range it's replacement is offered in. That would make sense.

I sure will be disappointed if I spend the ca$h on a 6.2L F-350 if they come out with the 7.3 gas in a year or two. I plan to actually keep my next truck for a long time, unlike the last few. Thanks for all the replies.

Pretty cool info provided by that link. Where is everyone expecting this new engine to be placed. Article says it will replace v10 but will it also replace the 6.2? Or will it be the base as the 6.2, the new 7.x in the middle, and then the 6.7 at the top? I can see where some people are coming from about their concerns with diesel but I'm thinking as the emission tech matures and hopefully with a little help from slowing down the ever increasing regulations, it will become more reliable.
One thing that im pretty sure about is that this new engine won't be $9k cheaper than the diesel, I think it will only be about $4k cheaper.
