Summit Racing™ Pro SBF Windsor Stroker Edition Big Nasty Hydraulic Roller Cams
Summit Racing™ Pro SBF Windsor Stroker Edition Big Nasty hydraulic roller cams are high performance camshafts for 1986+ Ford 351W-based stroker engines, designed for street/strip use. They offer a mean, choppy idle, high-lift profiles tailored for modern cylinder heads, and are machined from American steel. These cams typically feature high-RPM stability and aggressive profiles to maximize torque in performance applications.
Key features and specs:
* Engine fitment: Optimized for 347+ cu. in. Ford small block Windsor (351W) engines with roller blocks
* Performance profile: Part of the Pro SBF line which ranges from daily driver to 8k rpm cams; "Big Nasty" implies an aggressive, high-overlap profile for a rough idle
* Manufactured from American bearing steel billets on modern Landis CNC grinders
* Designed to be easy on the valvetrain while maximizing lift
* Often require 3.73+ gears and a 3,500+ stall converter
* These camshafts, alongside the 303+ Series, provide specialized, affordable options for Ford enthusiasts looking for both sound and performance—with specific Summit Racing Pro SBF/303+ cams being designed to work with modern valvetrains
