I have a question for all you. I know of a kid by me that has a 4.3 out of a 98 fullsize for sale for $200. Its in a few peices but runs and only has 35k on it. I figured this would be a good place to start building an engine so i dont have downtime on my truck which as of now is my daily driver(soon to change). He said its a W code but doenst know what that means and either do i. Is this the same vortech engine i have in my 99 x or is it different. Any info would be great. thanks

The "W" code is the 8th digit in the VIN. If your 8th digit in the VIN is a "W", I would say it was the same engine. The horse power rating might be different.

yeah, its just a diff HP rating, if its out of a blazer it should have about 190 hp. the 4.3 had Z, X, and W, codes.
