100% CNC'd 267cc GM LS3/L92 Cylinder Head Packages: GM's new LS3 head represents a phenomenal leap in capacity over previous cathedral port castings. In as-cast form this head moves only 313cfm at a whopping 260cc port volume. Keeping in mind that the LS3 is already a relatively large port our 267cc CNC'd package focuses on greatly increasing it's efficiency. Serious enthusiasts, racers, and some of the premier tuning shops in the country are reporting excellent gains thus far. What sets this package apart from many ported LS3 heads is the capacity for significant gains without sacrificing drivability, throttle response, and power below 5,000rpm. While the power gains are impressive, the largest gains are realized in the meat of the powerband. Where most ported LS3's on factory shortblocks are stuck in the mid 400's for peak torque, we've seen in excess of 480rwtq SAE! Below you will find a multitude of offerings based on this head. We can accomodate any application from basic budget oriented components to all out road or drag race packages. If you would like a different set of components or want a quote to perform our work on parts you already own please do not hesitate to contact us. More photos & recent results to be added ASAP.
