Skunk2 305-05-8400 is a Stage 1.5 Ultra BMF TLRC camshaft set for the Honda B series, ground from billet 8660 alloy steel with CNC cut roller lobe profiles. The intake cam gives 13.2 mm (0.520 in) of lift at 263 degrees of duration measured at 1 mm, and the exhaust cam primary lobe gives 13.08 mm (0.515 in) at 272 degrees. These are roller valvetrain camshafts, so they run with the Skunk2 Ultra BMF TLRC roller rocker set, part 348-05-0200, in place of the factory rocker assembly. Skunk2 validated the valvetrain on a spintron to 12,000 rpm using S2 ProXP springs, Skunk2 spring bases and Skunk2 titanium retainers, and notes that other combinations may give different results. The set suits naturally aspirated and forced induction builds.
