Summit Racing™ Pro SBC Big Nasty Stroker Edition Hydraulic Roller Cams
Summit Racing™ Pro SBC Big Nasty Stroker Edition hydraulic roller cams are high performance, American-made camshafts designed for small block Chevys, specifically tailored for larger displacement (stroker) engines. They feature aggressive lobe profiles for high horsepower, improved torque, and a strong, aggressive idle (14 degrees of overlap).
Key features and specs:
* Performance: Designed to produce significant power (i.e., 459+ hp and 458 lbs.-ft. torque in tests)
* Design: Hydraulic roller, 3-bolt, usually with tight lobe separation (105+3 LSA), suited for high-RPM power in street/strip applications
* Big Nasty specs: Features 0.550 in. lift with a 218/230 degree duration split (at 0.050)
* Application: Ideal for 383-400+ cu. in. SBC engines needing a powerful, aggressive camshaft that still uses hydraulic lifters, often requiring aftermarket valve springs and, in some cases, fly-cutting pistons
* Quality: Precision-machined on modern CNC grinders from American bearing steel billets
