I have a $300 5.3L from 2005 Silverado with 33K from ebay put a used Z06 cam and $180 ebay headers and got 326RWHP and 323RW Torque with 87 oct at 26 MPG and these 5.3L are everywhere and cheap. The truck motors are filling up salvage yards because they last well over 200K miles so there is not enough demand for replacement motors in stock applications. This means these are very reasonably priced buys for great power and fuel mileage. Car Craft recently did a built with a low compression LQ4 with GM L92 heads and got over 500HP. I have scene several 5.3L with under 10K miles with motor and trans for around $1000-$1500 and the 07+ are all aluminum with pre production Z06 heads and a higher compression ratio. It’s getting to the point that a LS swap is close to the cost of buying a GEN I 383 crate motor. I also deal a lot with the guys who run most the LS salvage yards and do engine locating services for any style LS engine from a low buck 4.8L to a complete LS7 Z06 drive train. Or you can always go to your local GM dealership and pick up a new crate motor with a warranty

Getting it in the car
All the new Gen III and Gen IV LS series engines feature a new bolt patern on the block for the motor mounts so none of the tradition methods will work in adapting it to an older application.

BRP came up with the Muscle Rod line of LS conversion kits that feature a lifetime warranty on the Poly frame mounts, which feature the first rebuildable design of its kind (Patent Pending).

The GM LH8 oil pan works great with OEM ACC and Low mount A/C
The Cadi CTS-V works with the KwikPerf.Com kit or no A/C
If going aftermarket the AutoKraft is great for any combo
