The COMP Cams CS 287Qs9 .900 base camshaft is built for 383 stroker street engines with quality heads, offering a very wide power band and a 2600+ stall converter recommendation. The .900" base circle provides extra rod clearance for stroker cranks. Its four-pattern design optimizes valve events across runner lengths for increased high-RPM stability and notable RPM gains; requires upgraded valve-train components.
