What 5.7 engine was used in 2500 series want to replace engine with a new crate motor dont know what to order

I am assuming you have the 5.2 liter (318 cubic inch) V-8. If the knocking is coming from the oil pan, you may be able to just replace the main and rod bearings on the crankshaft and the oil pump. It is a relatively simple but messy job dropping the pan. I did that job on my old Dodge Dart Sport 318 when it had about 150,000 miles. After I installed the 0.001" under sized bearings, the knocking went away and the oil pressure was back to where it was supposed to be. Make sure the crank surfaces are not damaged or you will be wasting your time. If you end up replacing the engine, the cost will depend on if you get an engine from the junk yard, buy a crate engine, or have the original engine rebuilt, and could run between $1000-3500.

It would depend on which engine you have and whether you need the complete engine, or just the long block. Look up Chevrolet Crate Motors on the internet. You should be able to get dealer prices on all their engines. You might look into rebuilt engines from local sources. Generally, rebuilt engines are only going to be long block assemblies. They will be a lot cheaper than a crate motor, but the warranty won't be as good. Personally, I would go for the new engines.

If it follows the normal big block chevy order, it is: 1-8-4-3-6-5-7-2



Hope helps (remember rated this).

The best thing to do in this case is look around at local junk yards if you want a used motor or u can go to a dealership and order a crate motor for your car. The good thing about not knowing anything about your car is that your vin number will tell them everything they need to know. Its located on the dash, driverside which is on a metal plate u can read thru your windshield. Just take that number into a dealership and ask for a "rebuild crate motor" if thats what your looking for. I did my best to answer ur question i hope thats what you were looking for.

On the chevy small block v8 the numbers will be on the left side of the engine look for a small step right at the head / block mating area. The numbers will be in the form of a ser# get that number and call a good chevy dealer and they can tell what engine you got. But any small block chevy crate engine will be a 350 or a 305. they will act the same as far as tune up and any vacuum hoses to the carb or trans. They interchange of a sort.

If you are using an EFI engine and the old computer module is still used, have it reset first. It may still have the data from the old engine. If you are using an old engine, you may have to do additional inspection and see if there are worn out parts. For crate engines (brand new) it would need a break in period, normally less than 800-1000 miles.

No, that sounds about right. Depending what's wrong with it, the simplest thing is to replace the whole engine. Sounds drastic I know, but it's not nearly as painful as diagnosing a seized engine.

You can shop around for 'crate' engines, and your guy could probably find a junkyard engine that would work. I'd recommend a crate motor though, they usually have a decent warranty.

Good Luck!
