Cylinder Head Guide: LS vs SBC vs BBC, Runner and Chamber Size, Plug Style, and Assembly

Amber 0 Comments

Choose a cylinder head by exact engine family and complete engine combination, not by runner size or chamber volume alone. LS, SBC, and BBC heads use different architectures, while runner volume, combustion-chamber size, valve package, spark-plug angle, intake compatibility, and assembly level all affect fitment and performance. Bare heads require additional components and preparation,...

LS Intake Compatibility Guide: Cathedral vs Rectangular Ports and 92mm vs 102mm Throttle Bodies

Amber 0 Comments

LS intake compatibility starts with the actual cylinder-head port family, not the throttle-body size or engine label. Cathedral-port and rectangular-port heads require the correct manifold interface, and a 92 mm or 102 mm throttle body still needs the proper flange, control type, electronics, intake tubing, and ECU support. Fuel rails, injectors, sensors, vacuum connections,...

How to Match Cylinder Heads, Intake Manifold, Throttle Body, Camshaft, and Air Intake

Amber 0 Comments
