The COMP Cams mechanical roller 300A-R10 is an Ultimate Pro Street cam suited to extreme street/strip applications. It creates a radical idle and is built for large stall converters or four-speed setups where high-RPM breathing is expected. Requires roughly 4000+ RPM stall or a four-speed transmission and about 11:1 or higher compression to perform as intended in aggressive pro-street engines.
