A new gas engine for GM heavy duty trucks is coming

[Groover]

A new 6.6L engine with 400hp and 450lbft of torque is coming for 3/4 ton through medium duty GM trucks. It will have all of the new fuel saving tech and seems to emphasize torque over horsepower. It is always nice to see more options for truck buyers.

Well, y'all nailed it! It is literally the best time in history for engine enthusiasts for both gas and diesel.
You can drive to your local dealer and walk away with a 4,5, 6,7, 800 hp gasser, or a diesel with almost 1000ft lbs, or a car that gets 40+mpg everyday. AND they're all relatively relaible.
All the bs, bashing one in favor of the other is either brnad loyalty, envy or inferiority complex, basically.
Bring on the 500hp factory big block trucks! And please put a few in shortbed half tons!

More HP and torque of this new gas 6.6 should make it work less in GM trucks where the truck weight is similar to previous years. It would be nice to see this 6.6 get a few more MPG than the 6.0.

Customers like me have decided diesels aren't the reliable anvil they used to be. They are fragile, delicate, and costly when compared to their predecessors. You won't find a 5.9L Cummins or a 7.3L IH that will limit you to 5 mph because it's out of cow pee, or because the exhaust choking device is clogged. Yes they're powerful, but no thanks.

I'll pay a 2-3 mpg penalty at the pump (for less expensive fuel mind you), for a bit less power and gain reliability, and avoid the OMG repair costs that are inevitable in any engine.

You sound overly optimistic about gas and overly pessimistic about diesel I must say.

You 2-3 MPG loss may be a bit optimistic. Also, you definition of 'a bit less power' and mine are wildly different. (HPs may be close, but 400 ftLbs vs 900+ is not a bit less)

The cost of the newer gassers are way more than you think....at least the tundras we have at work have been.

This is good news. I hope ford Chevy and dodge build large displacement v8s again and I do personally hope ford goes back to a pushed v8. When they went to their modular engines they lost me, even though I'm still a ford man at heart. If they go back to a push rod v8 I'll strongly consider a super duty when the time comes to replace my ram.

If you read up on here or anywhere on the internet, Ford and Chrysler have something in the works for large V-8’s.

Why does everyone including OEM’s talk engine displacements in that damnfool metric anyways?

Because it is too tough to wrap my head around having a 213 in my truck when my old Chevy sedan had a 350. ; )

[Lessmore]

I've had to deal with the metric system since the early '70's. However I find I covert metric to British Imperial System in my head. Liters and cubic centimeters to cubic inches...etc. Why, who knows, in my case the 'old' system of measurement makes more sense to me. That's what I learned at school and use exclusively for the first 20 odd years of my life until the metric system was used.

[noteven]

Well I figure “customary” weights and measures will never totally disappear because the metric system lacks the “exaggeration factor”. Who ever heard of taking a shot at a speeding coyote and missing him by a kilometer? You will always miss by a mile.
That thing weighs a ton! Not a tonne.
Or that fave reality TV unit of measure the “football field”.

285mm width tires on a 18 inch wheel.

Anyways GM is not installing a Ford spark plug engine are they?

We have accepted it privately, publicly we are against it!

yup, the ONLY countries NOT on the metric system are United States, Burma and Liberia.

Virtually all US mfg companies are converted or have converted to metric system for dimensions and fasteners. How many bolts and nuts on your Ford, GM or Chrysler are still SAE? not very many.

YES, there are a few items worldwide based on inch dimensions, but not many. many spark plugs, virtually all wheels diameters and a few other holdovers from the early 1900's but that's about it.
