Frequently Asked Questions
Sep 15, 2021
Is the Dodge 4.vii a Hemi?
The Dodge 4.7L V8 engine is not a Hemi simply information technology does have some of the features of the legendary five.7L Hemi and that has led to people affectionately referring to it equally the "Semi-Hemi". The 4.7L motor can be found in the Dakota and the Ram 1500 series and produced 310 horsepower in each of them.
A Hemi motor has a hemispherical combustion bedchamber in information technology. This is where the head of the cylinder is spherical inside and that allows there to be a higher compression ratio unremarkably than a flat head. The downside to a Hemi is ordinarily they only have 2 valves per cylinder considering it is more than difficult to fit the valves on the curved surface of the head.
Dodge has become famous for developing Hemi engines and that goes dorsum to their muscle cars where they were known to be able to get extra power out of the motors. The 4.7L V8 is a great engine for a small truck, just it is non a Hemi.
How much horsepower does a 4.vii V8 take?
Contrivance's iv.7L V8 has 235 to 310 horsepower depending on the vehicle that it is installed in. The horsepower deviation is primarily due to the different intake and exhaust designs that are used depending on the size of the engine bay.
The 4.7L V8 is capable of producing 295 to 334 pound-feet of torque which is pretty good for a smaller V8 like that. One place that the 4.7L V8 is not great is with fuel economy, they average about xiv miles per gallon in the metropolis and 17 on the highway. That ways if you choose a truck or SUV with this engine it will need to exist filled upward pretty frequently.
You can find the 4.7L V8 in the Jeep Chiliad Cherokee and Commander, the Dodge Ram 1500 serial, Dakota, and Durango, Chrysler Aspen, and even the Mitsubishi Raider. The engine was produced from 1999 through 2013 and so there are a lot of cars on the road that have them.
How durable is the 4.7 V8 engine?
The Dodge 4.7L V8 is a good, simply somewhat boring, choice in the world of Dodge engines. They should accept no problem lasting over 150,000 miles but they can go very finicky if you do not go on up with the maintenance on them. It is important to make certain that you get your oil changed every 3,000 miles and employ thin oil in the engine.
The engine has a cast-iron block that holds up very well and it has a timing chain that should last the life of the motor. That said there were some issues with the hydraulic lash adjusters. If whatsoever of these had any faults it could lead to the rocker arms getting moved and damaged.
In general, the four.7L is average in terms of reliability. I would not expect these to exist long-lasting 300,000+ mile engines. That said there are millions of them on the road and they are pretty easy to piece of work on so if whatsoever issues come they can be stock-still affordably.

In 03 I bought an 03 Dakota,quad cab,4x4 with fifteen,10*x miles on it from Executive Leasing. Fast frontward to 2013. I never abused or hotrodded this truck. One twenty-four hours I'm out running errands I shut the engine off to go into a store,come back out,fire it up and it starts ticking like a bomb. Turns out 2 rocker arms rotated off the push rods. At that bespeak I opted to install a new iv.7 not rebuilt. It came with a three year warranty. 4th yr head gaskewt blows. Replaced head gasket. That brings united states of america to 2022. Guess what's sitting in mydriveway with another blown head gasket. Yep the head gasket eating 4.7. All you experts with your"you have to change oil every 3000 miles and keep upwardly on your maintenance" just know you can do that and it will still eat your head gaskets!!!!
