Is my carb ok?

Hello,
I have a 360 LA block, J heads, mild cam, hooker headers, , A904 torqueflight with 3.91 suregrip, 2500Stall, currently 600CFM Edelbrock.

I have an edelbrock Performer RPM manifold I would like to install, in place of the performer 318/360. This manifold recomends a bigger carb, 650 cfm or more.


I have a Holley 4777 650 CFM double pumper, I am hoping I can make it work great,
I see most people talking about 750s being more ideal on an engine like this, and I also see people saying double pumpers are better suited for a manual. I hear people saying too big a car, kills response but gives more power on top end,

any takes on if this 650 DP would be great? can it be tuned well enough with my combo?
