Edelbrock Carburetors?

Here is my 2 cent take...

The Carter/Edelbrock AFB & AVS are square ore carbs even though there is a minor offset in barrel slengths size. As illustrated the spreadbore is the BIG offset design.

The aluminum carbs are super street friendly but should use a thick mounting gasket under them to help keep them cool so fuel doesn't boil out of them. Edelbrock sells such a gasket.

The AFB is fine though I like the AVS style better with the tuneable secondary door.

For you, thread starter, if it we're myself, it would be the small Edelbrock AVS electric choke style carb with there .333 (or so) thick gasket. A tuning kit, fuel line and filter.

There is zero power gain with a manual choke. There never was. It does provide automatic choke and help warm up the engine better, quick & faster for your ease of operation. It's a freakin win win!

I myself have also installed a Edelbrock electric fuel pump with relay kit for the pump and used the OE return line. It's easier on the pump and simple to use if you already have one, otherwise, don't worry about it. The pump is calibrated for there carbs so make sure you get the right one.
EZ to install. You'll spend more time figuring where to put the pump and wiring relay than installing it.

Constant cool fuel. Not issues. Allways starts right up. Home run!
