Hey Argo,
I went with the Holley HP 830 series with annular discharge (no horn/choke, etc). Previously I ran a regular 750, and there is a noticeable difference throughout the power band, but not at first. I had to rejet the HP down a little and go up on the discharge nozzles a bit to get it spot on for good throttle response. For some reason, my 830 carb came with larger jets than my friends 1000 HP carb stock from Holley. Depending on how well your motor flows air - you may need to do some carb tuning on the HP. If you are not sure what to do with tuning, find a great carb tuner (with your new carb on your car) to assist you to bypass having to purchase extra/multiple discharge nozzles, jets, pump cams, carb gaskets...and it saves time. Good Luck.
