Sbc Cam 284b-TL56 Tight Lash Solid

The Sbc Cam 284b-TL56 Tight Lash Solid from COMP CAMS is a mechanical flat tappet camshaft engineered for small block Chevy engines seeking aggressive street and strip performance. This cam delivers 0.540-inch intake and 0.550-inch exhaust lift with a 284/288-degree duration split, optimized for builds targeting 3,200 to 7,000 RPM operation. Tight lash design eliminates the need for hydraulic adjusters, providing direct valve train control and reliability for dedicated performance applications where consistent valve timing is non-negotiable.

The 106-degree lobe separation angle (LSA) creates a broad powerband while maintaining tight lobe phasing for efficient combustion and responsive throttle action across the rev range. Flat tappet design operates with conventional hydraulic lifters and pushrods, requiring no exotic valvetrain geometry and keeping total system cost lower than roller cam conversions. The solid lifter architecture demands precise initial valve clearance setup and regular rocker arm geometry verification, but rewards tuners with zero hydraulic compliance and absolute predictability under high-rpm load—critical for carbureted engines or early fuel injection systems where cam stability influences idle quality and fuel mapping.

This profile suits small block Chevy street machines, circle track cars, and vintage drag platforms where builders prioritize mechanical simplicity and valve train durability over maximum peak horsepower. Installation requires attention to proper pushrod length, rocker arm ratio matching, and static lash setting—tasks best handled by experienced engine builders or serious enthusiasts with dial indicator and degree wheel experience. Compatibility spans all small block Chevy variants (262, 283, 327, 350, 400 cubic inch) using traditional distributor-fired ignition and conventional intake manifold configurations.
