Carb Selection Help

[PNJSNAK]

Currently I have a 351 W .030 over, cast iron heads with a Blue Racer Crane Cam 204/214 at .050" lift, .030" over Federal Mogul Flat top pistons, hydraulic lifter, Edelbrock Dual plane manifold with a Edelbrok Performer Carb model 1406, 600 cfm w/vacumm secondaries and electric choke, Ford Durospark Vacumm advance distributor.
Never had it dynoed but told approx 325 HP.
The engine has been bullet proof, only changed the plugs and oil in 9 years, 15k miles. Runs great with no issues, plenty of power for me.
I am not interested in going for big horsepower change but when people look under the hood, they seem dis appointed with the Edelbrock carb. "What no Holley!" Also, I really don't think I need the choke, never take it out under 50degrees here in Northern Ohio.
I am looking for some suggestions on a new carb.
Choke, no choke?
Electric or Manual?
Mechanical or vacumm secondaries?
Holley model 4150 650 cfm #4777S or #82651
Barry Grant Speed Demon 650 cfm model 128201

Looking for suggestions and why.
I like the idea of the Holley 82651 with mechanical secondaries and no choke.
Is that a good idea, if no why not?

Thanks in adavance.

Jim
