4 Barrel Carb?

[Ol' Ron]

Adding a 4bl carb to am old flathead is just esthetics, you just on't need one unless you need the airflow for power. A single 2GC will provide all the air necessary for street, and more. Now for a reliable, easy to tune 4bl the 500CFM Edelbrock is the best one, they don't make a smaller one and you d need an adapter No mater wich carb you use you'll nees an AF meter and a n adjustable ignition system. tuning is the problem nomater wich carb you use. Personally I like the 390, the small primary makes this carb a great one for around town driving, and doesn't look bad either. Reguardless what carb you use reliability will be the issue. Recenly I had a problem with a 3 carb engine running rich nomater what I did. YEP!! bad air cleaners.

This was how I went with 276 cube and three Max built Strombergs and an L100 from Ol Ron. Runs great.
