What kind of engine does a Chevy 409 have?

The 409 V8 is a missing link, if you will, in the history of Chevrolet horsepower. The engine might be best remembered today as the subject of an old Beach Boys song, oddly enough. Still, the 409 is an unusual and interesting engine. Let’s jump right in for a closer look.

How are the valves aligned on a Chevy 409 V8?

Unlike the small-block Chevy and other V8s of the period, the W engine’s valves were not aligned in a single row but offset in two planes, which permitted larger valve diameters within the allotted bore spacing. (However, the valves were not splayed at multiple angles as in the later Mark IV big-block V8.)

Where is the oil dipstick on a Chevy 409?

On the 348, the oil dipstick is on the left (driver) side of the engine, while on the 409 the dipstick is on the right (passenger) side. As a mid-year, high-performance offering, the 1961 version of the 409 is relatively rare. Only 142 cars were built with the $484 option, which went into production in January of the model year.

Can a 348 crankshaft fit in a 409?

The main and rod journal diameters and other features are the same as the 348, but the 409 crankshaft will not fit in a stock 348 block due to its larger counterweights. The 409 block is also thicker in the cylinder walls to support the .187-in. larger bore diameter, naturally.

When did the Chevy 409 V8 come out?

Chevrolet 409 V8 Engine The Chevy 409 V8 was introduced in December of 1960 as the engine of choice for the all new 1961 Impala Super Sport. It was put into production by GM because of the performance ground that had been lost due to the new highly successful Ford 390 that had been gaining respect at the local race tracks the same year.

What’s the deck to bore angle on a Chevy 409?

Chevrolet’s offset placement of the valves was possible because of the deck angle on the 348 and 409 engine block. Traditional V8 engines utilize a 90-degree deck-to-bore angle, but the deck-to-bore angle on a W engine is a 74-degree angle.

Can you tell the difference between 348 and 409 engine blocks?

Therefore, since the 348 and 409 oil pans are somewhat interchangeable, identifying a block using dipstick placement is not 100-percent foolproof. If the block has had one or both of the heads removed, checking the bore can provide solid clues.

How big is the cylinder head on a Chevy 409?

There are no limiting factors that we are aware of when our heads are used on the ’61 through ‘65 409 blocks.” We all know that cylinder head flow is crucial to create power, and a set of stock “high performance” 348 and “low performance” 409 cylinder heads use 2.06- and 1.72-inch valves, and flow roughly 210 cfm.

Before the era of big-block Camaros and Chevelles, Chevy fans seeking high performance in a passenger car package opted for full-size cars equipped with 409 cui V8 engines. Drag racers favored the lighter and more rigid two-door sedan Bel Air and Biscayne versions.

What’s the difference between a 348 and a 409 motor?

The oil pans from 348 and 409 motors have an interchangeable bolt pattern, but are different. While that may sound confusing, think of it this way. The oil pan of a 348 can’t always be used on a stroker motor as it is slightly narrower than those made for 409s.

What was the stroke size of a 1964 Chevy truck?

Starting with a 1964 truck 409 block and crankshaft, the motor’s six quart oil pan, .060” overbore (final bore size of 4.375 inches) and the stock 3.50-inch stroke, the combo ended up as 421 cubic inches.

When did Chevrolet stop making the 348 car?

Chevrolet continued making the 348 to use in trucks, going into 1965. In fact, because the 409 was introduced in early 1961, the 348 was offered to car and truck buyers for more model years than the 409. The 348 ran from 1958 through 1965 and the 409 was produced from 1961 through 1965, or seven years to four.

The 409 V8 was introduced along with the new Super Sport model in December 1960, a few months after the other 1961 models. It was a direct development of the Chevy 348 “W” big block engine first introduced in 1958. Initially available with a single four-barrel carburetor, it produced 360 horsepower, which was bumped to 380 for 1962.

Where was the 1964 Chevy Impala SS 409 made?

Like its 1960 Impala stablemate, this SS is a largely original car. The numbers-matching 409 V8 was cast on May 21, 1964, at the Tonawanda, NY engine plant. The finished engine was then sent to the Van Nuys, CA plant for installation. This Impala was built during the third week of June, 1964.

What kind of carburetor did a Chevy 409 have?

Chevrolet needed the 409 to keep up at the drag strips. There was only one version of the 409 in 1961. It was the 360hp. It was equipped with solid lifters, high lift cam, and a 4-barrel Carter AFB carburetor. In 1962, a 380hp could be had. More importantly the 409hp 409 with 2 4-barrel Carter AFB’s was now available.

What kind of engine does a 348 409 have?

The 400hp 409 came with a single 4-barrel Carter AFB carburetor, and the 425hp 409 with 2 4-barrel Carter AFB’s. These same three engines were available for 1964 however it would be the last year for the 425hp version. In 1965 the 340hp and the 400hp 409’s were the only sizes available.
