Would like to replace entire engine block on my car. 2000 Chevrolet Impala

My car is pretty old and the engine has finally failed. I really like the car and does not want to get a new car, but instead would like to gut the car and replace everything with newer parts. (I know it will be costly and to most not worth it, but i have my reasons). How would I go about buying and replacing the engine block? (Will not be doing labor myself)

My car has 250000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there – the most straightforward way to replace (and even upgrade!) your existing engine, is to simply purchase and install a "crate" engine from GM. These are new motors, with a warranty serviced by any GM dealer, which come in an astound number of configurations, from stock, period-correct bolt in replacements, to high performance replacements for increased power. Let your checkbook be your guide. Crate engines are available, to your door, from after market suppliers like Jegs and Summit Racing. Your neighborhood service center or mechanic can then install it for you, and you’re back on the road! Unfortunately, this is not a service YourMechanic offers at this time. Thanks for thinking of us though!

Yes, you absolutely can. the process for it is a little difficult and takes some time but with the right mind and money, you can most definitely fit a V8 into the impala.
If you`re just swapping the engine out and it literally bolts right in, you can expect to get the job done in a weekend. If you`re good, you can do it in somewhere between 5-8 hours of work. You can expect about the same thing (2-3 days) if you`re taking your car to a mechanic for a regular engine swap for maintenance.
How long does a Chevrolet Impala engine last? Your engine is what keeps your car running, so its life expectancy matches the Chevrolet Impala for between 150,000 to 200,000 miles.
The engine will fit in place but you will need to change over the transmission and all of the electrical and the computers. Once that is done then the computers will need to be professionally reprogrammed to be able to work. This all can be done, but you cannot simply just swap the engine over.
You can, but I wouldn`t recommend it if you like the car. On a modern car, it typically, it isn`t worth it. Even on platforms where there is a V8 option, switching from a V6 to a V8 can be a major hassle.
V6 vs V8: Horsepower and Torque

In theory, by design, a V8 will always be able to make more power than a V6. That`s what those cylinders are there to do, and two more of them is an advantage.

This is due to the fact that V-6 engines have two fewer cylinders. V-6 engines have improved performance compared to V-8 engines, especially when timing acceleration properly because there`s less tendency to drift to the outer edge.
Do Chevy Impalas last long? A Chevrolet Impala could last between 200,000 and 300,000 miles with proper care and maintenance. Further, a 10-year-old example has a potential lifespan of around 230,343 miles with a remaining life expectancy of nearly 50%.
Unfortunately, there are more bad years than good ones for the Chevrolet Impala. Buyers will want to focus on examples from 2015-2019, 2012-2013, and 2009-2010. Avoid these Chevy Impala model years: 2014, 2011, 2006-2008, and 2001-2005.
It depends on the cause of the reduced power. Often, the problems are minor. In rare cases, though, reduced power can cause more serious problems like a seized engine, or even an electrical fire.
Shut off the engine, wait 10 seconds, then restart the vehicle to see if this resets the reduced engine power light—but this will only work if it`s a signal error. Avoid driving your vehicle when the reduced engine power light is on—instead, identify and repair the underlying problem that`s causing the warning light.
V6 vs V8: Horsepower and Torque

In theory, by design, a V8 will always be able to make more power than a V6. That`s what those cylinders are there to do, and two more of them is an advantage.

If you want to buy a newer model, the top speed of the Chevrolet Impala is right around 155 mph. While the powertrain of the Chevy Impala has changed drastically over the years, a 3.6-liter V-6 with 305 horsepower and 264 pound-feet of torque is what propels the Impala to its max speed.

ANSWER : Hi there – the most straightforward way to replace (and even upgrade!) your existing engine, is to simply purchase and install a "crate" engine from GM.

I took an engine from a 2002 Dodge Intrepid and put it in a 2000 Chrysler 300M do I need to leave the fuse block under the hood fr
ANSWER : Hi there. I wish we could really help you, but the reality is that this type of engine swap always has issues like you’ve described, but the fuse box is only one part of the issue you’re going to have to deal with.The main issue is due to the fact that the ECU and electrical system in the original vehicle does not connection correctly with the newer engine you have installed. Having engines link with the existing ECU happens about 50% of the time. The only way to resolve this problem is to contact a dealership, purchase a new ECU and have them program it to the new engine. In regards to the fuse box, replacing one from the vehicle, not the engine is best.

Should I buy an Acura tl 2009 with an engine replacement at 70k miles?
ANSWER : If a used engine was installed, to make a wise decision you would need to know exactly how many miles were accumulated on that used engine PRIOR to its transplant to the car that you are looking at. However, if a "new" engine was installed, then you might have the opposite of a red flag which is a good deal but even that depends on whether the "new" engine was actually properly installed according to the instructions. The only real "red flags" in a car purchase are collision damage (whether such damage is repaired or not stay away), rust, abuse, and lack of maintenance. Consequently, the mere fact that a "part", even a part as big as "the engine", was replaced is not important. What is important is whether the part was PROPERLY installed and, in your particular circumstance, if the part was "used", exactly how many miles were on it prior to installation in the present car? And, of course, is the engine presently functioning well (it can be tested and evaluated, to some extent, during an inspection).

With regard to any used car purchase, you want to confirm that the vehicle has NEVER been in a collision (Carfax might be helpful) and that the vehicle does not have any outstanding recall-related repairs. Apart from that, inasmuch as used car repair, maintenance, and restoration costs are highly dependent on the actual, as found, condition of the vehicle, the only way to get a reasonably precise estimate of costs you might face, and also to protect yourself in the transaction, is to request a pre-purchase vehicle inspection. That inspection, carried out by a certified Mechanic, dispatched to your location, will give you the exact data you need to make an intelligent, informed decision about any car. If you look at the just cited link for YourMechanic’s inspection service, you will see a long list of the vehicle systems that must be inspected as well as details of YourMechanic’s inspection methodology. If you need further help, please do not hesitate for a moment to re-contact YourMechanic and we will assist you further in your attempts to make a wise used vehicle purchase.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.

Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.

To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

My car doesn’t respond to the gas pedal like it should
ANSWER : Hello, thank you for writing in. The engine is likely sensing an issue and compensating for it. When you restart the vehicle, the component may be passing its start up tests, and the engine stops trying to outperform itself. Start by having the vehicle scanned for diagnostic codes. If there is another sensor to blame, it may show up there and make diagnostics a lot easier. If not codes come up, you will want to test the fuel pressure available at the engine, and make sure the fuel system is working properly. You can also clean the throttle and test the throttle position sensor. For more help with diagnosing and resolving the issue, contact our service department to schedule an appointment.

1998 Lexus es300. Can no engine compression mean bad computer and not engine replacement?
ANSWER : An engine computer cannot control, or affect, "basic" engine mechanical compression, that is the level of cylinder compression measured in a static test. Even in the complete absence of any engine computer, the basic specified compression of an engine will exist. If the engine doesn’t have the minimum specified compression, then the engine is mechanically broken. If the timing belt on the engine is in the correct position, the SOLE determinants of engine compression, during the typical static test, are: 1) the condition of the cylinder walls and the piston rings; 2) the condition of the engine valves and valve train; and 3) the condition of the head gasket. Consequently, if the engine has no, or little, compression during a test with the throttle held open, there is a mechanical problem with the engine, not an electrical problem. I would first check to be sure the timing belt has not slipped; that fault alone can ruin compression. If the timing belt has not slipped, and you desire a run down of your options to get this resolved, please request a rough engine operation diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.

Stock engine swap replacement compatibility
ANSWER : The engines (i.e., the long block assemblies) from the two subject VIN’s are 100% interchangeable. Please note though that sensors, electronics, controls and accessories on the engines would have to be separately verified OR, without verification, simply carried over from your old engine to your "new" engine just in case there is a variance in the PCM (that controls the engine) from 2008 to 2010. In certain select locales, YourMechanic professionals will perform engine swaps, or sub-parts of the work. Finally, you obviously want to be sure that your existing engine is not repairable in situ, or perhaps even easily repairable once removed. If you want to explore the possibility of repairing what you have, simply request an inspection and diagnostic and the responding certified Mechanic will help you with this.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.
