==Holley squarebore carb==
 +
The squarebore 4bbl Holley is a very flexible carb. The design of the model 4150 and 4160 squarebore Holley 4 barrel carburetor has changed very little since its introduction in 1957, and the design and tuning techniques remain basically unchanged as well. They are easy to rebuild, tune, and they have great aftermarket support- in fact a "Holley" carb can be assembled without using any Holley parts.

The model 4160 Holley 4 barrel carburetor. Along with the model 4150, its design has changed very little since its introduction in 1957, and the design and tuning techniques still work on most of the newer ones. Easy to rebuild, easy to tune, and having LOTS of aftermarket repair and hop-up parts, the 4bbl Holley may be the best choice for you!

===Fuel transfer tube===
 +
Holley redesigned the fuel bowl transfer tubes and seals used on the 4160, 4150/4175, and 4165 carbs. The old style used a simple rubber O-ring on a transfer tube that had a collar on both ends to secure/locate the O-ring. This design was leak prone and somewhat troublesome.
 +
 
 +
The new design has a straight tube without the collar and a new type of seal. Details are shown in the photos below.
