The Blazers are based on the S-10 body and frame. SO IN REALITY, it is a S-10 Blazer. This is a way to identify a Full size Blazer (which is now called a tahoe!) or a smaller Pickup truck sized blazer. Everywhere I go, I get asked if it's a Full Sized or S-10. I always tell them it's an S-10. As a matter of fact, I don't even wait for them to ask me. when I order parts, or anything for the Blazer, I tell them it's a 1997 S-10 Blazer, 4.3 liter V6 "W" engine. They know everything from there.
