forged LS3 shortblock RSS
HPR 442 Another Koenig design, the 442 LS3 by HPR. Erik's custom forged rotating assembly give this stock LS3 engine block a full liter more of displacement without costly re-sleeving processes. The increased displacement will mean much more torque not found with the typical 402/414 builds that are commonly found. Finish it off with a custom top end package by HPR or fit your own components to suit your build requirements.
