GM Planning larger gas engine than the 6.6L

I think in the mid2000's when the 8.1 was available the take rate was low. However now that diesels have gotten more complex, expensive and due to that complexity less reliable, the gas options is more appealing then it used to be.

Wasn't it about 20 years ago that GM had an 8.1 Gas engine that they put in their pickups? A guy I worked with bought one for hauling his 5th Wheel and he really liked it. For some reason, though, GM discontinued it. Might've been the poor fuel economy.

I have a 2002 with the 8.1... LOVE IT...

Big GM V8, clicky of link above

It seems like it is aimed at Class 7 trucks. My guess more specifically garbage trucks and delivery trucks used in big cities and using CNG for fuel. You lose about 20% of your power with CNG so the bigger engine is needed.

We had a couple of BIG Chevy engines in the firehouse back in the early 80's.

You needed a fire hose from a fuel farm to feed it.
