New Thunder Carb. ?????

I just got a new 800 Edlebrock Carb. for my 383 RoadRunner, who else is using these carbs? It seems to run a lot better now but I haven't drove it yet. I have just started and ran it in the shop and it idles and starts really good. Let's hear about your experiences with these. Ronnie

I'm running one on my 408. Had to jet the primaries down two stages or to #22 on the tuning chart. that's it. Runs great..
