The COMP Cams CB 47S Tl292A-8 camshaft is specified for 427+ engines and works with high compression ratios (11:1+), pairing best with a 4000+ stall converter. It targets big-inch, high-compression drag and pro-street applications where aggressive valve events and higher stall speeds are required for peak power. Note: BBC 1965–1966 396 c.i.d. engines with a rear-journal oiling groove are incompatible with the listed part numbers.
