yeah not much difference, but your truck is heavier plus has the 4l80e tranny so that alone kills alot when comparing it to the SS, i would suggest a custom tune and a small cam for that big pig and it should really wake it up, a 212/218 will work well in that heavy truck...

I've owned both.... you'll need a lot more hp mods than the SS just to keep up. But, getting a custome tune instead of the Diablo would be a good place to start.
+1, def a good idea!

Diablo Tunes aren't bad for the price. Go on the DiabloSport website and go to the Forum there, and Mikel or Johan will make you a custom tune, usually FREE. Mikel is a great mechanic and tuner, and Johan works for Diablo.

Depending on the year, if it is pre 05 the connecting rods are beefier in the lq9. If it is 05-after only diff is pistons lq9 flat tops- lq4 dished. Heads are the same.
