237/25X .619"/.619" 117 LSA
The new BTR Small Twin Turbo cam was designed for use with smaller twin 66-76 mm setups or up to a single 94mm turbo in 388-427 cubic inch combos. This cam is recommended for street/strip type applications looking for more power and rpm , and offers an aggressive idle. This cam uses ultra stable lobes for higher RPM potential, and was designed to be extremely durable at high rpm when combined with a lightweight valvetrain.
Due to higher rpm potential combined with greater cylinder pressure from boost we recommend the use of our SK703 spring kits and larger diameter hardened pushrods along with a quality lifter such as a Johnson ST2116LSR or ST2126LSR.
