Chrysler 440 V8 Engine

In the mid 60s the muscle car battle between the Big Three automotive manufactures was getting heavy. With the success of the Chevrolet 409, GM was planning to unveil the 427 for the 1966 model year. Ford had already released their 427 in 1965 to do battle with the already very popular Chrysler 426. So Chrysler decided to raise the bar another notch to fight the competition by developing the 440 V8 engine for 1966.

The Chrysler 440 V8 engine was built from 1966 to 1978 and was the last of the Mopar engines that were over 400 cubic inches. The 440 was definitely not as powerful as the 426 HEMI but considering it could be purchased for half the price of a HEMI there were a lot of buyers ready to purchase this Mopar powerhouse.

From 1969 to 1971 the 440 got even better with the introduction of the “six pack” carburetor setup. This setup was 3 dual carburetors that were designed so that the center carb fed the engine when cruising down the road and then when the customer really wanted the extra power they could simply stomp down on the gas and the other 2 carbs would open up and give the engine everything it needed. This allowed the car owner to get better gas mileage on the highway as well as maximum performance at the drag strip. The “six pack” setup pushed the horsepower up to 390 and was used in many of the most popular Chrysler, Dodge and Plymouth muscle cars of the late 60s and early 70s. This included the Dodge Super Bee, Plymouth Road Runner as well as the Plymouth Sport Fury GT.

Virginia ran the 440 magnums in their State Police Cars. The 1971 would top 165 (the speedometer would go all the way over and bounce. The HUGE 1976 that weighed about 5000 pounds topped at 145+ (checked by RADAR). It got 6 mph cruising and 4 mph or less in pursuit. With its racing suspension it was wonderful to drive around the mountainous roads. The 71s had a dual point distributor and the top speed was determined by the skill of the mechanic in setting the points and timing. They had a 4 bbl carb. The front two barrels were about the size of a quarter, the back silver dollars. Thus, the saying, you "might" (I never lost a race) outrun my 440, but not my RCA (radio). We used to judge the speed by how far back the 6' whip antenna on the back fender folded back at top speed.

440 Magnum was so under rated
I definitely agree with Tony T. posting Riding in the 440 Magnum Is a Ride to Remember (for sure)The advertised horsepower so under rated But it sure wasnt 375 or 390 Horsepower It well exceeded those Oh ya the 426 Hemi held ground but unless it was tuned by a professional technician the 440 Magnum would Kick Its Butt,If you ever get to ride in a 440 Magnum Go For It,You WILL Remember the Ride.

Downsizing 440 in 1973 RV to ?????
Hi,

I have a working 440 V8 in a 26 foot 1973 Winnebago and am looking to swap out the 440 for something smaller. I have looked at the newer 5.9L but wonder if with the weight saving, I could something else.

440 Magnum
Noticed in article where said the 440 Magnum was definitely not as powerful as the 426 Hemi well the 440 Magnum was So Unrated its now coming Out what the Actual Horsepower was and It was not That uncommon for a 440 Magnum to Take a 426 Hemi if you ever get to ride in one you just have to it's a ride you'll remember.

426 street charger
Dodge made a 426 street charger that was a 440 with a slightly smaller bore-It was rated at 365hp-I know because I bought one new in 1964-This 426 became the 440 after it was bored .030 over.
