1,050 HP, 6.0L Single-Turbo LS - Complete

This is a lot of power for the money!We kept costs down using seasoned GM block and heads that we have redone from top to bottom on our CNC machines. Extraordinary performance at a great price is delivered by our integrating outstanding parts with our precision machining, assembly and dyno tuning.The crank we use is a stock-stroke, forged Callies Compstar with 8 counterweights. The additional counterweights increase overall stiffness by about 25% and reduce harmonics so that the crank does not want to flex as much. Bottom line is that the engine lives longer because crank bending and twisting under heavy load is minimized. The forged rods are Callies Compstar Extremes. These are topped with Diamond R series dish pistons.The top-end features seasoned GM LS3 heads that we port our 5-axis CNC. We also machine the combustion chamber to optimize for boost. The valve job and bowl blending is done on our Newen CNC. The heads are assembled with our custom hardware and COMP BSR shaft rockers f
