I'm looking to go from an Edelbrock 800 to a 4150 type Holley.

The rundown on the car and combo is a 67 Belvedere, 727, 451 with Edelbrock heads ootb, RPM intake, 10.5 comp, .520-254 solid cam, 9.5 converter, 4:10. This is street car but not interested in an electric choke as I have never used one being in Phoenix. If I decide to go that route it seems this time of year is as about as cheap as I am going find prices.

What carb would you guys recommend here?
