I bought this for my 4-71 blower and 270 Hemi but I decided to go back and use a single Gilmer belt drive instead. Pulleys are new, never mounted. The last picture is just for reference only, so you can see how it looks on other blower setups. Included: Idler pulley, snout pulley, crank pulley and hardware. $425 plus $25 shipping. Payment via PayPal business transaction.
