hello all , i cant seem to find this info anywhere , do all; the second gen 96 scfpi and up to 2005 blazers use the same throttle body ?

 

The thing to do is a part-number cross-reference. Rock Auto makes this pretty easy to do. You can also do this at an online GM parts vendor.

 

tried that , no luck that’s why I asked here

 

Dang!!

 

You can go to TascaParts.com and run the different years yourself to check, but it looks like there is one PN for the 96-97, another for the 98-99, and two others that are applicable to the 2000-2007 4.3L engine (yes, 2007 as the 4.3L was used in the full-size trucks during and after the s-series production).

Now...what changed? Without having one of each of them in front of me, I can't say for sure, but I would bet it was minor casting variations through the years as a pattern was updated due to wear, etc.
