Flat torque curve with a LQ4?
I just got a 2004 2500 after looking at new Tundra's and Titan's. What I would like to know is what can be done to a 6.0 to have a torque curve like a Tundra or Titan? I know they are a non pushrod motors and they have they're advantages but is there a certain H/C/I combo that could be bolted on a 6.0 that could come on strong off the line and not taper off till 6k rpm?

I'd say with something like a 212-218 comp cam and a cheap set of 243 heads to raise your compression up and a tune for all of it you will whoop on some tundras and tow better than stock. You could do all that for about 1300 and gain about 75-85 horse and equal torque. Or if you don't tow heavy **** alot you could go a little bigger on the cam, or get the heads ported and help power all over.

I'm not sure what you mean by flat torque curve. The lQ4/LQ9 already has a flat torque curve, mine makes plus or minus 25 ft/lbs or so from 2500 to 5800 rpms. If you are talking about low end torque, the above advice is outstanding. LS6 heads to raise compression and a 210/218 or 212/218 cam to really get some more low end power. Also, you may consider 4.10 gears if you dont have them already.

By flat torque curve I mean from 2000 rpm to redline. 90% by 25-2800 rpm. After driving all of them, the Tundra/Titan feel stronger way down low. But with the mention head/cam combo I can get 400+ hp and tq (rwhp?) and get a possible 20mpg highway, that sounds like the route I'm looking for. Does this require and fuel delivery enhancements? If I was to change 1 thing, either the heads or cam, which would give me more bang for the buck and lean more towards my goal ( I plan on both but which one first)?

Are the LS6 (243?) heads similar to the 317 heads I have now except for smaller CC to raise compression? Do they flow the same? How much would they raise the compression?
