dual carbs?

[Redcap]

My intake is a 4v cast iron job. I don't remember the number, but there was a D, a 5, and a T. 1975 truck?

4bbl CAR intake.

A marine engineer in Arizona?!

I guess I should have said ' a marine engineer currently endeavoring for an AAS Degree at a sub-standard community college program in Arizona'

Understand the engineering behind carburetor selection:

The number of barrels is by itself an irrelevant measure. The useful factor is CFM; 'cubic feet per minute' of air flow into the engine.
Whether you achieve, for example, 600 cfm through 2 or 4 barrels, the engine depends on the 600 cfm and NOT the number of barrels the air flowed through in getting into the combustion chambers.

One barrel, two barrel, tri-power, six-pack, four barrel, dual quad, throttle body, TPI, whatever, the engine requires a quantity of air and couldn't care less how many barrels the air has to flow through to do its job.

That being said, it is a fact that more barrels typically enable greater quantities of air to flow and that is why you see multi-barrel carburetors or multi-carburetors being utilized on larger displacement engines.

I am a marine engineer by trade and appreciate the verifiably proven science behind the numbers of internal combustion engine operation.

Why do I like these old Fords? The simplicity baby, the simplicity.

Interesting. The SBF's, SBC's I have seen all had four barrel carbs. The one FE I ever remember seeing in person (I have probably seen more in the past but didnt know what it was other then a Ford) had a four barrel carb. The 302 in my friends F100 has a two barrel carb.

In my mind a two barrel carb just seems small. Tho most of my engine experience centers around racing.

My 67 f250 had a 4 bbl on the 352. I got that truck in 76. It had a cast iron manifold.

[DIXONBOY]

I could have sworn my friends 69 F250 camper special had a stock 4bbl on it. But i could be wrong.

[64squire]

I also thought 4 bbl's were available in 69, but after a little web research it seems that they weren't put on
trucks until 1975-76 390's.

Yup. 75 truck intake. I have one on the 390 in my 67 and a spare one stashed.
