I have a perfect Holley Street 650HP d-pumper carb. This is the high peformance double-pumper version that has no choke and has the smoothed out entries into the venturis for better airflow. It has the screw in air bleeds for tuning and has a 4-corner idle system. It has the chrome like finish. My son ran this on his 85GT and then decided to go custom. It is all original except we added the notched rear float kit with jet extensions. The carb is perfect in every way and has very few miles on it. It sold new for $525+ with the float kit, but I will take the first $275 for it. I also have the Holley 750HP main body conversion kit that allows you to upgrade to a 750 by just swapping the main body and jets. The main body kit sells for $135+, but I will sell it for $50 if you buy it with the carb. I have the original instructions for the main body and the 650HP carb. I have pics if you send me your e-mail address. contact me at aarongardner@verizon.net or 419-965-2856 I am set up for paypal also
