How to Pick The 460 Carburetor?

The 460 is a famous big block engine that underperformed, but is still a classic of the automotive history, and appears in many Ford applications including marine. The best option is to buy a 600 to 750 CFM carburetor to maximize the power capabilities of this engine.

The 460 was a less popular model to the 429 that saw extensive use and was popular in many applications.

The 460 Bore x stroke is 4.362 in × 3.85 in (110.8 mm × 97.8 mm), it comes with four different chamber sizes, and these include:

75cc C8VE/C9VE/D0VE
89.5-92.5cc F3TZ
~93-95cc D3VE/E8TE
~99-100cc D2VE

There are 2 valves per cylinder, and the actual label was 460-4V – “V” stands for “venturi” which is a barrel and represents the carburetor capacity.

The 460 engine was large and heavy and was surprisingly weak for all its capacity, where size in engines usually denotes horsepower, other factors come into play that contributes to the overall power of an engine. In the 460 model the horsepower output was only 385, and by 1973 the engines were only putting out 70% of this power.

In terms of size, the 460 is 34 inches by 27 inches by 30 inches and weighed in at a whopping 720 lbs. This truly made it a “big block” engine. Consider the power to size and weight ratio; this is a serious underperformer.

The 460 outlasted its 429 smaller brothers, and continued production well into 1996, 23 years longer than the 429 that stopped in 1973.

Let’s take a look at the top-rated carburetors for the 460 (385 engine family).

How to calculate your Carb requirement

The formula for calculating how much CFM (cubic feet per minute) an engine requires is:

CFM = Cubic Inches x RPM x Volumetric Efficiency ÷ 3456.

When you apply this to any engine, consider that the volumetric efficiency of stock is 80%, a slight upgrade with average bolt-on have a volumetric efficiency of around 85%, and race engines will range from 95% up to 110%.

To calculate the CFM requirement of an engine would then look like this:

460 engine x 4,600 max rpm = 2,116,000

2,116,000 x .80 = 1,682,800

1,682,800 ÷ 3456 = 490 CFM

This means that the best CFM for a 460 would be around 500, anything over will deliver performance improvements, anything significantly under will stall.
