Preferred carburetor for mild 360?

Edelbrock AFB....1405 or 1406....depending on if you want Electric or Manual Choke.

(1) gasket.....
(2) metering rods
(4) Jets

Simple.

make sure you use an Isolator Gasket under the carb for less heat absorbtion...into the body of the carb.

Like said above....there are too many variables to diagnosing a "rough idle".

Ignition System:
Spark Plugs - gapped to .035"
Spark Plug Wires
Distributor Cap and Rotor

Then its just a matter of setting Initial Timing at where the engine likes to crank the best....I use a Vacuum Gauge and set the Initial wherever the HIGHEST and STEADIEST vacuum reading is....then..Set the Idle to around 800rpm-900rpm.....then the idle mixture screws need to be set....and you do that by baseline'ing the screws to 1.5 turns out from seated....and adjusted each side OUT till you hear a Raise in rpm, then IN till you hear a Drop and average the position between the two....ON EACH SIDE.

I would run a Edelbrock over a Holley on a "primarily street driven" vehicle.
They are SIMPLE'er.

You think tuning a Edelbrock is hard.....wait till you have to really dig into a HOLLEY.
