small block 283 64/67
its Chevy 454 Big Block Engine
Repost the question and add the suffix code.
It will be in the suffix code stamped on the block. If it has a "CE" in the suffix code, regardless of displacement it's a replacement block. CE stands for "counter exchange."
Don't know what the letters stand for, but I found that suffix here: http://www.nastyz28.com/gm-chevy-codes/chevy-engine-codes-suffix-6.php It shows on the chart what that engine was originally used for.
The way to determine the engine size, horsepower rating, and transmission mounted to it is the engine suffix code stamped on the block in front of the passenger side cylinder head. It is a three letter code. For example, an LS6 454 with a 4 speed transmission will have an engine suffix code of CRV. The VIN code will only tell you if the car had a V8 or L6 installed from the factory, but it won't tell you WHICH V8 or L6 was installed.
there is no suffix for why or suffix code
Engine, not motor. It's a GM small block - probably the 5.7 liter/350 CID - but all GM small blocks with a 4.000" bore used that casting code at some point. Not sure what the second number is. It doesn't look like a VIN number or block suffix code. To know for sure what you have, look on the front passenger side of the engine. There'll be a small machined pad which will give you the block suffix code. Those numbers will tell you the year, size, horsepower rating, carb used, transmission used with it, and the type of vehicle it was mounted in.
the gsr engine will have a code on the block in plain view that reads b18c1 or b18c the h22 will have a similar code on the block but it reads h22
You will need to provide the suffix code from front on the passenger side head of the engine.
This is a warranty replacement engine. There are several decoders for the block numbers for these engine on the web and all require the block serial # as well as this code.
