Información
Las culatas de la serie Speedmaster LS se encuentran en rápida expansión. La plataforma LS (Gen3/4) ofrece numerosas ventajas de diseño con respecto a los diseños anteriores de motores SBC, especialmente en las culatas. Si bien las culatas GM son excelentes, hemos desarrollado una línea superior de culatas para los entusiastas del rendimiento moderno. Al igual que todas las culatas Speedmaster, las culatas de la serie LS se fabrican mediante nuestro proceso de "Fundición por Gravedad". Este proceso garantiza una fundición más uniforme y robusta, sentando las bases para la construcción.
