(runningforcover)Well both are great engines to have in a truck, but I would go with the lq9 becuase of the extra torque it produces over an ls1. (more cubes) Trucks are heavy and need a the most impulse possible of the line. (torque
) Plus you can later get a 4.000" crank and bored piston cylinders to 4.030" and have a 408ci torque monster. 
Just my 2¢.

Are you buying a "package" ? I had a 4.8 but killed it and so I went with a used LS1(02') shortblock that had like 12k miles on it becuase I got a real good deal on it and a buddy of mine was selling it. If I were to buy brand new I would go with the lq9/lq4 becuase they are cheaper and have a tad but more power. I love my LS1 though and Im very happy with it. The only advantage ot has over the LQ's is its 75 or 100 lbs lighter being ti has an aluminum block!

Go with the LQ9. I have one in my 2005 ECSB truck and love the torque.
With even the factory cam it seems to have a lot of potential for future add-ons. A factory LQ9 with a good custom tune, exhaust, CAI kit, will propell you into the mid 13's. With traction of course.
The 20" wheels and tires on my truck slows it down quite a bit. I ran a 14.32 in the 1/4 mi with traction problems.
There are guys that post here that say when they change out the 20's to a lot smaller wheel and tire combo, they are dropping 1/2 sec. or more.
These are ext. cab trucks too. If you have a single cab short wheel base, then you will of course see a bit more of a drop in the E.T.
