You are looking at a Rochester Quadra jet 4 bbl Carburetor # 17085238 HTB and dated 0656 which is March 1986. Removed from an 86 Blazer with 305 4 speed. Correct for late 1985-87 Chevy & GMC truck, Blazer & Suburban with 305 or 350 with manual trans. Very complete. Secondaries are frozen. This is a virgin core for rebuild. Even comes with the truck LONG air cleaner stud.  

I WILL NOT USE USPS FLAT RATE BOXES.
