Looking for some serious power at a great price? Look no further! This 6.0L LS long block is designed to handle up to 1,000 hp. It is an upgraded version of the long block used for our 645 hp naturally aspirated LS. Both use seasoned GM 6.0L blocks that we have re-machined on our CNCs to far tighter than the original GM tolerances. In this boost ready build, we use a forged Callies Compstar center-counterweighted crank for additional strength and stiffness along with the same Manley H-beam rods. In this case, the Platinum Series pistons are switched from flat top to dish to complete the short block. This drops the compression ratio making it pump gas friendly under boost.
The COMP hydraulic roller cam is designed for boost and brings maintenance-free operation. The exquisite CNC port work we do on the RHS aluminum heads provides great airflow with bronze-bushed rockers for reliability and durability. A FAST LSXR intake manifold can easily handle the intended boost and adds a great look to your engine. It's paired with a FAST Big Mouth throttle body assuring that this baby can get the air to those heads.
This long block as a complete engine is rated at 600 hp without boost, as it is giving up compression compared to its 645 hp rated, naturally-aspirated sibling. Externally, the two long-block builds appear identical. We would of course be happy to build either into a complete engine if that's what you want.
The price includes everything as shown from oil pan to the lifter valley plate and GM valve covers along with an NA break-in session on our dyno using our intake manifold, fuel rails, etc. Give us a call at 815-725-2727 to discuss your specific needs. We have a range of options including packages with the turbo, engine management & serpentine systems as well as the transmission. This set up can also be ordered as a short block.
