INTAKE LOBE LIFT @ TDC: 0.07821

The new BTR Big Twin Turbo cam was designed for use on 82mm or larger twin turbo setups or single 102-106mm turbos in 400-427 cubic inch combos. This cam was designed for use in high horsepower,max effort applications looking for more power at higher rpm , and offers an ultra-aggressive idle. This cam has the potential to push a 400" engine well over 2000 rwhp and into the 6 second range in the quarter mile. This cam uses ultra stable lobes designed in house and Spintron tested 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, larger diameter hardened pushrods, and a quality lifter such as a Johnson ST2116LSR or ST2126LSR.
