Hello i have an engine from an 2002 blazer. it is a 4.3 vortec with a vin code W. what years will this engine fit into? i have heard 96 and up. is that correct? Also have a 94 vortec engine for sale with 93k on it. make me an offer. I also will sell the 02 engine if anyone needs it. Please let me know what years the 02 engine will fit in, i would appreciate it.

i beleve 92 to 95 was a cpi injection, 96-01 was scfi, and im not sure as to the 02, that may be a different bread of scfi
