Mixed bag for sure. I bought it originally because it was about the only carb intake on the market back when I did my swap. I never could get my carb tuned to work with it, but I also didn't spend a ton of time. It just had a bad habit of falling on its face whenever you stabbed the throttle. It would roll into it okay, but hard hits just stalled the engine entirely. I was running a Carter AFB at the time and almost got a Holley double pumper, but I think I needed a spacer to make the linkage clear.
