Q & A

What's in the Box

This throttle shaft converts throttle linkage to 1:1 ratio. Better throttle response and HP. Fits Holley 4150 carbs.

Note:  Throttle linkage only fits carbs with 1-11/16" throttle bores.

Ford/Holley 94 Extended Throttle Shaft
                        

About the only way your 94 carburetor could have a tight throttle shaft would be if you found a NOS carb somewhere. Now you can build yourself a dual or triple carb three deuce set-up that will run like new. We offer you these new extended throttle shafts that are .282" which is .005" oversize. You simply run a 9/32" drill bit or reamer through the base plate and you now have a tight carb again.

Includes (4) throttle butterfy plate screws and a 6-32 x 1/4" truss head end screw (slotted head).
