Carb choices?
 

I am trying to find the right carb and need advice, I dyno'd this combo at just over 400 hp but I am not satisfied with the Edelbrock. I think I might be over carbed, but not sure. Let me know what you think I need with this set up:

SBC 350 bored .30 over
Comp Cams Marine Extreme Cam 218/226 238-2 is the part number lift with these rockers is 508 528 Crane Blazer Roller Rockers 1.6
ProAction non vortec heads 180 cc runners and 64cc combustion chambers Hypereutectic pistons zero gap rings 9.4 compression, zero deck height block 202 160 valves
Edelbrock Performer RPM manifold with an Edelbrock 750 carb manual choke, vacuum secondaries.

I have been spinning this up to 5400 RPMs
I am partial to Holley carbs, let me know what you think.
