Description

EC 319VS Billet Velocity Stack – Fits Tillotson HL-304WX, HL-348D/E, HL-355D/E, HL-360B/C


Upgrade your carburetor’s intake system with the EC 319VS Billet Velocity Stack, engineered for optimal performance on Tillotson HL-304WX, HL-348, HL-355, and HL-360 series carburetors. Designed with a carefully contoured internal radius, this stack smooths and accelerates incoming air to enhance velocity and boost carburetor signal—improving throttle response, fuel atomization, and overall engine performance.


Unlike standard filter adapters, the EC 319VS is built to deliver maximum airflow efficiency for high-demand racing and performance applications. It complements the venturi design of these carburetors, ensuring consistent and reliable intake flow.


Each unit is CNC-machined from aerospace-grade 6061-T6 billet aluminum for superior strength, precision, and durability. All necessary mounting hardware is included for easy installation.

Note: Velocity stacks are not legal in every class. Please consult your racing rulebook before ordering.
