Test Your Dodge Knowledge!

At the Dodge Facebook page, we posed a test of knowledge for you Dodge experts. Here it goes:  The 1970 Dodge engine lineup included two 440-cubic-inch V8s with four-barrel carburetors. One 440 was rated at 350 horsepower; the other at 375 hp.

 

So: What were the differences between these two famous Dodge 440 engines?

 

Spoiler alert: the answer follows below, so if you don’t want to know yet, stop reading now.

 

The “standard” (if you will) Dodge 440 four-barrel that year had a bore and stroke of 4.32 inches by 3.75 inches, and used a single Carter carburetor, producing 350 hp at 4400 rpm.

 

The high-performance Magnum version sported the same bore and stroke and other key specs, including the Carter four-barrel carb. But the Magnum was upgraded with a windage tray, a heavy-duty timing chain, and a more aggressive camshaft with greater valve lift and duration. Thus equipped, the Magnum was rated at a whopping 375 hp at 4600 rpm, and 480 lb-ft of torque at 3200 rpm.

 

In fact, with just two exceptions—the 440 Six Pack and the legendary 426 Street Hemi—the 440 Magnum featured the highest power rating of any regular production Dodge V8 for a few years.

 

An additional bit of trivia: the Magnum 440 engines generally were marked at the factory with the letters HP (standing for “high performance” in Dodge lore) on the cylinder block adjacent to the distributor. If you knew that, be sure to give yourself some extra credit.

    In 1980, I was 17, and saved and borrowed to buy a seen better days 1970 Plymouth GTX with a 440 Super Commando engine. I think that was the Plymouth version of the Dodge Magnum engine. Loved the car, even though it had been through the wringer.
