What can I expect from a cammed LQ4 or LQ9
Looking for either an LQ4 or an LQ9 for my Fox body project, what can I expect from either of these engines with mild mods - cam, bolt ons, exhaust?
Will they make 350rwhp with these mods?
Stock heads, intake, etc...
Thanks

Thanks guys
Here's the deal - ready to buy now and I have a few options
2003 6.0 out of GMC Sierra and 2003 6.0 out of Silverado - i'm guessing these are LQ4's?
Both have 122k and 114k respectively
The other option is a 54k 2005 6.0 from an Escalade - this is the LQ9 correct?
the 2k3 engines are $850 and the 2k5 engine is $1000
LQ4 has lower compression because of dished pistons versus the higher compression LQ9?
Which engine? Are the truck intakes sufficient for the time being or do I need to invest in an intake ASAP?
Sorry for the confusing (newb) questions but i'm completely in the dark on these engines.
Thanks

I'd go 2005 if a turbo isn't in the future.

If you can swing the LQ9, do it, if you are worried about the intake get a used LS1 intake, the truck one is very tall and wont fit under the stock hood. I got a LS1 intake for $30.00, then modified the fuel rail to work. See my Photobucket for info.

Both engines are complete and come with the truck wiring harness. The ECM's I have access to as 2 of my very closest friends are Bryan Herter and Keith who own PCMForLess, so the tune and ECM part is no problem.
This engine is going into my 86 Mustang - currently has a 2 1/2 or 3" cowl hood on it so I should be ok with a taller intake.
The car was previously a turbo 306 and future plans are to go back to running a turbo - however, the pistons and rods would be replaced regardless. I want as much power as I can put out n/a in the meantime so it looks like the LQ9 is going to be the best route - according to what i've been reading.
Stock block 306 w/ 67mm Precision turbo, Redneck C4 with 15lbs boost the car made 525/626 and ran low 10's all day
Here's the car as it sat this year prior to SBF/C4/Turbo removal

I just got mine running a week ago, so it still has a long way to go for tuning.
LS2 heads - 243 castings (bumped up CR to 10.5)
Lunati cam 227/231 .651 lift
42lb injectors
stock LQ4 everything else with 78,000 miles on bottom end
It's a BEAST! Puts my previous 350 to shame (around 400/425 hp/tq at the flywheel)
still puts out 35PSI oil pressure at hot idle, and at cruising speed is up around 55PSI
