Barry Grant Speed Demon carb that I've had for a while. This thing is like new! I bought it, and put it on a LS7 for a day. I couldn't get it to perform like the Edelbrock I was running, so on the shelf It went. This is the big 850 cfm, with 1.75" butterflys, removable venturies, and fuel bowl site glasses.
Still have the video, manual, and stickers with it. Sale, or trade for something I need.
Of course, I'll make a suitable donation to the site, when it sells.
