Carburetor replacement help

[Rudedawg]

Hey all...just bought a 73 Luxury Lemans. All I need is a new carb. Does anyone know the type of Holley that would work well for my 350? Looking to switch from 2 bb to 4 bb. Thanks much.

You have to change the intake manifold to mount any kind of 4bbl, are you aware of that?
Do you also intend to use an aftermarket air cleaner assembly?
If you do change the carburetor and intake did you want a spread bore or square bore carburetor and intake?

Also possibly the fuel pump. FYI you will not get much of a performance increase by just changing to a 4bbl carb. For a 73 you will get a bigger performance increase by changing out the factory rear gears, (usually 2.42 to 2.78) to something like a 3.23. And a camshaft change would help more than a 4bbl carb.
