The motor I got from the salvage yard comes with a 1 year warranty. Remember torque is just as important as horsepower.

 

i agree... if you do alot of work with your vehicle i'd recomend the 6.0 or can't afford a stall to go with it. the 5.7 is a great buy, but in LS6 form it's going to need a stall to make it pull decent out of the hole at all. it would be nice to have the lower weight of the LS6 though. tough call on the two.

 

really? the 6.l heads are that good

 

I didnt know that you could get a one year warranty frrom the junk yard.
Thats cool. yea you are right about the torque thing.

 

Just see what patriot says about LQ9 6.0 heads. It does not mention the LQ4, but the LQ4 heads are the same casting as the LQ9.

Patriot performance LS6

 

I find it hard to believe that your are going to make 65hp from a cam swap in a 6.0L., and if you did, you would have to sacrifice a TON of streetability and drivability. With that being said, I would still go for the cammed up 6.0L with a Radix for the same money. My 6.0L (LQ4) was $1600 new (EBAY) and the true LS6 complete motor (which you would want for the intake, throttlebody, injectors, etc) is in the $7000 range. The LS6 swap is cool, but so is a blown 6 liter. ****, no matter what way you go you'll have a bad **** on your hands! And everyones' doin' 6.0 Liter swaps, the Z06 motor would definately be something different.

 

All I am tring to say is, everything being the same, as in intake truck or LS6, exhaust, etc, the 6.0L will make more power. A cam swap in a 5.3l can gain 30-45+RWHP. You can't belive factory numbers, example a 5.3 is rated at 295 HP and a LQ4 6.0 is rated at 300HP, gm would have to detune the hell out of the 6.0 (as in computer) to get it down that low.

 

LS6, 3200 stall, 4L80e, 150 shot <--- my plans
