440 Carb advice

Hello, It has been a while since I have been here. New Job, working more hours. A friend is putting together a 440 , basically stock 70 Cuda with exhaust manifolds, an Edelbrock Performer RPM, and prefers to run a Carter AVS. He currently has a rebuilt 700 CFM Carter AVS, but is looking at a New Edelbrcock Thunder AVS in the 800 cfm configuration. He has tried Holleys and Demons, all without satisfaction, so he refuses any of those carburetors. Do You believe this New Thunder AVS will be ok for this application? Thanks for your advice.

Regards,

Ariovistus
