I run a 750 AED (modded Holley) double pumper on my 410 and run 11.44@114. Could it use more? Maybe so. I’m good. Runs outstanding on the street. If you’re not drag racing or trying to wring every last bit of power out of it I wouldn’t go any bigger. Give AED a call and tell them what you have, they’ll give you a good real world recommendation. Oh, and if you want the most out of whatever carb it goes without saying to read up and learn how to tune it.:thumbsup:
