60-Degree GM V6 Camshaft

The WCF61 High Performance Engle Camshaft from West Coast Fiero is specifically custom-ground for their application, designed to enhance performance in 60-degree GM V6 engines. This camshaft is compatible with 2.8L, 3.1L, and 3.4L engines, and works particularly well with modified 2.8L engines and 3.4L engine conversions. Engineered to maintain intake manifold vacuum at idle, the WCF61 ensures proper operation of the MAP sensor and consistent power brake vacuum. It features a lift of 0.440 inches, a running duration of 256 degrees, and a duration at 0.050 lift of 210 degrees, with lobe centers at 112 degrees. The camshaft's upper limit is approximately 6,000 RPM, though this can vary based on other engine modifications such as headers, intake manifolds, head work, and compression. This camshaft was developed to not require valve spring replacement and utilizes stock pushrods. Installation is recommended to be "degreed in" for optimal performance, and cam timing, lift, and duration specifications along with cam lube are included. While direct consumer purchase from Engle Racing Cam is not available, West Coast Fiero offers this exclusive custom grind. A minimum of a 10HP increase is expected, with potential for more depending on other engine modifications. The source also recommends replacing the timing chain and notes that new lifters are a must for installation, suggesting Eaton high-performance hydraulic anti-pump-up lifters for best performance.
