I have a 383 that was dyno'd at 450 hp/468 ft lbs of torque. I run an Edelbrock 750. I know I probably could have made few more hp with a Holley, but I like the Edelbrock because I can get 20 mpg with it out on the highway. Any of the carbs mentioned will work well for you. It essentially boils down to a matter of personal preference.
