Are you looking to make serious horsepower with a light-weight aluminum block that will survive? The Dart LS Next2 tall deck (9.750 inch) aluminum block with 4.125 inch bore is an ideal foundation. This upgraded version of the LS Next skirtless block features Ford Cleveland-style mains with 1/2 inch main studs, 1/2 inch head studs, a raised cam location and 0.904 inch lifter bores.
The rotating assembly features a Callies Ultra billet crank with 4.250 inch stroke and Callies Ultra H-beam rods. These are topped with custom Diamond pistons designed for 12-degree, Mozez-style valve angles. This combination with the tall deck yields a displacement 454 cubic inches with pistons fully supported throughout the stroke. The reluctor wheel is replaced with a Holley billet-steel crank trigger to work seamlessly with available Holley engine management systems.
This short block comes with BRE custom 0.904 inch mechanical lifters featuring needless bronze bushings and Cometic MLX head gaskets because we know they will hold together.
While great parts are necessary for a great build, let's not forget machining. Your block will be 100% CNC machined for perfect dimensions and finish. Our CNC hone is able to produce an exact match to the surface finish called for by Diamond for this ring package with a precision impossible to match with any manual hone. That translates to more power and a longer life. Check out the video to learn more.
