BBC Tunnel Ram Linkage

The BBC Tunnel Ram Linkage by Enderle is a precision throttle control system engineered for high-performance big block Chevy engines running dual quad carburetor setups in tunnel ram manifold configurations. This side-mount linkage assembly synchronizes two carburetors simultaneously, ensuring balanced fuel delivery and consistent throttle response across both intake runners. Built for serious engine builders and drag racing enthusiasts, this component transforms aggressive manifold packages into streetable or track-ready power plants by eliminating hesitation and mechanical binding.

Constructed from a combination of aluminum and steel materials with black anodized and zinc oxide finishes, the BBC Tunnel Ram Linkage resists corrosion while maintaining lightweight efficiency—critical for tunnel ram installations where clearance is tight. The dual quad design coordinates progressive opening across both Dominator carburetors, preventing one carburetor from outpacing the other during acceleration. The side-mount configuration allows flexible installation angles that adapt to various engine bay layouts without interfering with intake manifold geometry, while the mechanical advantage ratios are optimized for Dominator tuning characteristics and throttle pedal feel.

This linkage kit is indispensable for big block Chevy owners building tunnel ram platforms—whether for bracket racing, street performance, or exhibition vehicles requiring multiple carburetors. Installation requires basic mechanical knowledge and fits standard pedal assemblies used in hot rods and race cars. The compact footprint (13.9 inches in length) accommodates tight engine bays while maintaining full throttle travel authority. Compatibility is confirmed with Dominator carburetors in dual-quad tunnel ram configurations; installation should be verified against your specific engine bay layout and carburetor spacing before ordering.
