The greatest part is that it would out 60' my Z06 (on street tires of course) and out run it to about 35 mph.
Yep it was a crazy combo. I say "was" because I just pulled the 6.2L/6L80E out and put the 6.0L/4l60E back in. I need to buy a bigger truck unfortunately to tow my trailers. The 6.0L/4L60E seems like a complete turd compared to the 6.2L/6L80E. Well, I guess it is a turd, it doesn't even come close to running with my car. I still think the hp rating on the 6.2 must be conservative because it feels a heck of a lot more than a 60hp difference.

Do you think that just the addition of the 6l80e to the LQ9 would really wake things up?

The 6L80E would make a pretty big difference in my opinion but there is something to do with the engine. The LQ9 feels downright lazy when revving compared to the L92.
To put it in perspective...
With the short tires I have on my truck the 6L80 shifts into fifth gear just before the end of the 1/4 mile. A comparatively powerful engine with the 4L60 would only about half-way through third gear. What I mean is I have two extra shifts with an average of about .4 seconds each before the 1/4 mile is over so as great as the 6L80 is the L92 also has to be a factor with the elapsed time.
Correction to the fifth gear statement and the time -> my best run came with moving the shift points up so the trans wouldn't shift to fifth before the run was over. When shifting into fifth I was hovering in the 13.0x times. I bumped the shift points up to eliminate the extra shfit in the hopes of getting into the 12's.

I honestly don't know. The heads are awesome, the intake and throttle body are freaking huge and the cam really comes on above 2500 rpm and doesn't fall off (though I was only revving to 6200). I think it might be a freak because it should take about 400 rwhp to motivate a 4500 pound vehicle to nearly 105 mph in the quarter. The L92 is only rated at 403 crank hp. I made several runs and was never below 103 mph.

Sadly, I have the 6.2L/6L80E out and a 6.0L/4L60E back in. I am getting about 19 mpg with the 6.0L but ultimately I need to move up to a bigger truck for towing my trailer. I am certainly going to miss the L92.
