Intimidator X series

X380 Intimidator world formula alky


X380-5K EC Intimidator X380 OHV Briggs World Formula Kit

1.125 Throttle bore 1.000 Venturi.

This is the only 1.125” (28.575mm) Carburetor built for OHV Open Engines. Where the others fall short are in their initial design and intent for other engine applications. While all things are possible, the X380 is a far superior carburetor from start to finish. Our Intimidator Carburetors replace our 3+3 Twlight Zone Custom built Tillotson carburetor($600-1000+) with a blank body ready for any fuel circuit and modifications to fit any type engine. These carburetors are built with custom plate stacks, billet needles, and our EC signature 3 piece throttle shaft.


The X380-5K is designed for the Briggs World Formula.
