How to Choose The 351 Windsor Carburetor?

The 351 Windsor Characteristics

To allay any confusion with these names, the 351 cu in (5.8 L) Windsor featured a stroke of 3.5 in (88.9 mm). The 351 Windsor shared with the 289-302 models the same bell housing, motor mounts, and other small parts. The 351W had a unique, tall-deck block, larger main bearing caps, thicker, longer connecting rods, and a distinct 1-3-7-2-6-5-4-8 firing order. The dry weight of the engine was increased by 25 lbs to accommodate for the firing adjustment.

The 351 Windsor distributor is designed to accommodate a larger oil pump shaft and a larger oil pump. It had a unique head that optimized torque over high-rpm breathing.

Between early 1969 and 1970, the 351W heads had larger valves and ports. Between 1969 to 1974 the head castings and valve head sizes were 18 mm, in 1975 and up this was reduced to 14 mm.

After 1977, the 351W and 302 shared the same head casting, the difference being the bolt hole diameters which were ½” in the 351.

Between 1969 to 1974 the blocks were stronger than the later models, and in 1980 Ford changed the intake manifold to a four-barrel version with casting ID E6TE-9425-B. In 1988, the carburetor was replaced with fuel injection. In 1994, roller camshaft/lifters added.

The block continued to evolve, and in 1971 the deck height was extended from 9.480” into 9.503” this lowered the compression ratio. In 1974 the right cylinder bank was given a boss, which was used to mount the air injection pump, and they moved the oil dipstick tube too. The rear main seal was changed from a two pierce unit to a one-piece component in 1984.

The 351W 1969 model delivered 250HP (186Kw) and used a two-barrel carburetor, and also had a 290 HP (216Kw) model that used a 4-barrel carburetor.

Coming into the 1990’s the speed density method was replaced with MAF, this improved performance significantly. Today, most 351 Windsor engines are heavily modified for performance output.

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:

351W engine x 4,000 max rpm = 1,404,000

1,404,000 x .85 = 1,193,400

1,193,400 ÷ 3456 = 345 CFM

This means that the best stock CFM for a 351 Windsor would be around 350, anything above 400 will deliver performance improvements, anything under will deliver stock performance.
