How do I identify a 5.7 Chevy engine?

Identifying a 5.7 Chevy Engine
To identify a 5.7 Chevy engine, you can follow these steps:
1. Look for the Identification Number on the Engine Block:
– The identification number consists of a seven-to-eight digit code. The prefix consists of five digits and explains the date and the location of the Chevy’s manufacture. The suffix provides the size, model year, and the horsepower of the Chevy engine. The suffix can be either two digits or three digits.
– The identification numbers on a Chevy engine with a small block V-8 are adjacent to the cylinder heads on the passenger’s side, close to the front of the engine block. Look closely because the alternator might conceal it.
2. Check the Casting Number:
– Look for a second casting number on the rear of the block. This number represents the displacement of the engine. A 5.7L code, for instance, means it is a 350-cubic-inch engine.
3. Interpret the Engine Code and Partial VIN:
– The engine code and partial VIN will accurately identify the engine. The other information will fall into line with that. The partial VIN will match the vehicle’s VIN. If it does, it’s “numbers matching”.
4. Consider the Valve Cover and Heads:
– Vortec blocks used a late model center bolt style valve cover. These Vortec heads were also used on late model Chevy L31 truck engines.
5. Consider the RPO Code:
– If your vehicle is a Gen 5, and your 8th digit is a C, you have an L83. Naming convention between LS/LT/Vortec does not matter once you have the RPO.
6. Check the Suffix Codes:
– Suffix codes are stamped into a small boss on the front passenger side of the block where the head and block meet. There will sometimes be two lines of numbers and letters, later engines had just one line of numbers and letters.
By following these steps, you should be able to accurately identify a 5.7 Chevy engine.
