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

A complete intake and top-end build should be matched from the engine outward. Start with displacement, compression, RPM range, and vehicle use; then choose compatible cylinder heads and camshaft, match the intake manifold to the head ports and operating range, and size the throttle body, intake tube, and air filter for the airflow the...

Intake Manifold Guide: Plenum, Runners, Single vs Dual Plane, Hi-Ram, EFI, and Carbureted

Amber 0 Comments

Learn how an intake manifold distributes airflow and how runner length, runner area, plenum volume, and port design influence the engine’s usable RPM range. This guide compares single-plane, dual-plane, Hi-Ram, EFI, and carbureted intake manifolds while explaining cylinder-head port compatibility, throttle-body or carburetor fitment, fuel-system requirements, and installed-height considerations. It also covers LS cathedral-port...

Throttle Body Guide: How It Works, DBW vs Cable, Sizing, Cleaning, and LS Fitment

Amber 0 Comments

Learn how a throttle body controls airflow, compare drive-by-wire and cable-operated systems, and understand why bore size alone does not confirm compatibility. This guide explains throttle body sizing, bolt patterns, TPS and IAC requirements, intake-manifold matching, and key LS swap fitment checks. It also covers common dirty throttle body symptoms, professional diagnostic steps, safe...

Engine Air Filter Guide: Types, Fitment, Symptoms, Replacement, and Performance Filters

Amber 0 Comments

Learn how an engine air filter protects the intake system, how to choose the correct replacement by exact vehicle fitment, OEM cross-reference, dimensions, seal shape, housing design, and media type, and how to avoid confusing an engine air filter with a cabin air filter. This guide explains common filter types, dirty air filter symptoms,...

Cold Air Intake Kit Guide: Fitment, Tube Size, Heat Shields, Installation, and Filter Care

Amber 0 Comments

This article explains the selection, installation, and maintenance of cold air intake kits, emphasizing that proper vehicle-specific fitment is more important than intake tube diameter alone. Key compatibility factors include vehicle year, make, model, engine type, MAF/MAP sensor position and orientation, throttle body connection, PCV system routing, and available engine bay space. Any mismatch...
