I have a 770 Holley Truck avenger that I bought for my 86 K5. I just sold the truck, but kept the carb. I don't really have a need for it, so I'm selling it. It worked great on the truck, and is in excellent condition. It was on for no more than a year, and probably less than 5k miles. Let me know if you have any questions. I'd like to get $280 but I'm open to offers. Thanks ~ Mike
