Serious difference in compression and piston top design. Plus super heavy rods for a gas operation and heavy gear train up front. It wouldnít be a good choice.

Iíve been running direct injection 2 stroke sleds for awhile now. Technology seems to work. Much more efficient and better engine control reducing fuel consumption. My only worry is in the top end with the cylinder cutout. Hopefully it works better and lifter issues are no longer an issue like it has been in its smaller brothers.

So now we have a 6.6 liter LS? My oh my I'd bet it would respond well to a Magnuson tvs2650...

I've looked into it a bit, it is a upgraded 6.2, they added water jackets to cylinders and iron blocked it. I'm willing to bet with boost it will be an animal especially with the 6l80 behind it. I would think 1000 hp will be very easy with it...

4L80 would be much better.

Yeah but add power to it and forget it. I heard tuning on the 6l is a nightmare, if it isn't perfect it won't last whatsoever.
