Experienced mechanics share their insights in answering this question :
Hi there. You can use any engine from 2003-2008 Dodge that was equipped with the same engine. In 2006 they used two different 5.7 engines so it would be important to check the engine code to make sure that it will match. You can also use the one out of the Durango with the same engine code.

1997 will interchange with a 2001 on pretty much all parts. So you should have no problem getting that 01 transmission to work with that 97 5.9 engine. 94-01 the engines and transmissions were litterally the same. 39 people think this is helpful.
With over ten years and counting, the VCT 5.7L HEMI V8 engine has been used in Chrysler 300C, Jeep® Grand Cherokee, Dodge Durango, Ram pickup trucks, and Dodge Challenger R/T and Charger R/T models. So, there`s plenty out there waiting for a new life between the fenders of a cool old Mopar car or truck.
The Hemi family is legendary for its dependability very dependable. However, it`s the 5.7L Hemi that stands out as the most reliable Ram Truck Engine Option. Even the no-compromise Hellcat Hemis are solid, going 100,000 miles or more without issue.
Fuel Economy of 2021 Ram 1500 Engines

The 5.7L V8 engine gets an EPA-estimated 17 mpg in the city and 25 mpg on the highway. The 3.0L Ecodiesel engine gets an EPA-estimated 26 mpg in the city and 33 mpg on the highway. All of these engines are very fuel efficient and will help you save money at the pump.

5.7-Liter Hemi V8

The Hemi V8 will continue to be the Ram Truck engine of choice for all 2023 models. This is of course until the new Hurricane engine, with higher horsepower and torque, replaces the Hemi V8 starting in 2024.

So is RAM Dodge? While they are produced by the same parent company, RAM and Dodge are now separate brands.
Its 5.7 liters of raw energy shows up as the standard engine for the 2500 and features a hemispherical combustion chamber (hence the name Hemi). It makes 345 horsepower and 375 pound-feet of torque – or about enough power to launch a missile – and more than GM`s 6.0-liter V8.
With power going to the rear wheels, the Challenger R/T 5.7 Hemi can sprint from 0 to 60 mph (97 km/h) in 4.8 to 5.0 seconds, depending on whether it is equipped with the eight-speed automatic or six-speed manual. The quarter-mile blazes by in 13.6 seconds at 103.6 mph (166.7 km/h).
The factory rods are powdered metal with a cracked cap design and can handle about 650 hp. If you`re getting forged pistons, upgrade to Forged Connecting Rods at the same time. The OE cast crankshaft can handle about 650 hp and 7,000 rpm (for a limited time).
Still considered a small-block engine based on displacement, the 5.7L Gen. III Hemi uses a hemispherical combustion chamber with two spark plugs per cylinder and small wedge flats along with excellent intake and exhaust ports.
Most 2021 Ram 1500 models are standardly equipped with the 3.6L V6 engine, and can be upgraded with any of the other available engines. However, the 6.2L supercharged HEMI V8 is powered by the 2021 Ram 1500 TRX, the only trim that can be equipped with this engine.
A Chrysler Hemi V8 is a good buy, but the 5.7l version is one of the best. It`s powerful enough with nearly 400 hp, and that`s without modifications. It`s a rare beast of a V8 just at home in a big city luxury car as in a construction site truck.
The 3.6 L FCA Pentastar V6 Engine is an overwhelmingly durable and reliable engine. That`s why it`s been used in in more than ten million Chrysler, Dodge, and Jeep vehicles since 2010. With proper maintenance the 3.6L Pentastar engine can provide years of reliable service.

Under The Hood

The 5.7-liter HEMI provides 395 hp and 410 ft-lbs through an excellent 8-speed transmission. The eTorque system ($2,295) adds 16 hp and 130 lb-ft of torque, which really helps with fuel economy but only if you have a light right foot.

hi, I need some help to decide weather to purchase a 2000 dodge ram 1500 magnum or a 2003 dodge ram 1500 small engine
ANSWER : On the 2000 magnum you can expect to pay $500 on tires. If the 2003 had an overheating issue, whether or not it get fixed is a concern. The 2003 is a newer vehicle even though it has 15k more miles. My best guess could possibly not be very accurate, since it comes down to the condition and how good they look to me.

I would recommend having a professional mechanic do a complete pre-purchase inspection on both trucks in order to give you an idea of the problems they may have. Afterwards you’ll have the information to make an informed decision.

Trying to change 2002 Dodge ram 1500 5.9 ltr engine with 2000 Dodge ram 1500 5.9 and motor mounts don’t line up
ANSWER : Hi there. Although the engines are the same size internally, it is very common for manufacturers to change the location of engine mounts both on the engine and the interior of the engine compartment. Unfortunately, this type of swap would require some fabrication of the motor mount location in order for it to fit correctly.

Check Engine light on. Would the computer give all error codes in one shot? How do we know the engine’s condition?
ANSWER : Hi there. From the description you have provided, I’m am inclined to agree with your assessment of a used engine being installed in your vehicle. An inspection of the engine, by a qualified technician could determine whether the engine is sound. The Check Engine Light on and having a TPS (throttle position sensor) code does not necessarily mean the sensor is at fault. Circuit tests should be performed to confirm the fault. The likelihood of the ECM (electronic control module/computer) giving you all the codes at once is remote. Other component failures could occur. Address those as they come up. Even though you already made the purchase, I recommend having your vehicle inspected by a certified technician so that you can get a thorough evaluation of the car’s true condition.

When you can’t start a vehicle when it’s hot, the most common sources are the fuel pump, spark plugs, cap + rotor, coil, fuel filter, starter, battery cable, or a wiring harness fault.

Are the powertrain control modules in a 2004 Dodge Ram and 2008 Dodge Ram the same?
ANSWER : The powertrain control module (PCM) part numbers for the 2004 and 2008 model year trucks are different. So, it’s possible that the PCM could be the problem. However, there are countless things that could have gone wrong with an engine swap like this. Just one wire being left disconnected could cause all kinds of problems, including those you describe. I recommend taking the vehicle back to the shop that did the repairs to demand they make things right. If that doesn’t work, the team at YourMechanic would be happy to diagnose and repair your Dodge.
