Dual 4 barrel Carbs

Aussiespeed is always looking at new products and to complement our range of performance intake manifolds and supercharger manifolds a new range allows inline 6 cylinder and at a later day V6 and V8 guys to fit twin 4 barrel carbs to most engines. Part number will be AS0139


Some will say why would you want to drown an inline 6 with dual 4 barrel carbs ? An engine needs air and fuel needs to be metered to match the airflow and 2x 600 Holley vacs set up with the secondries either disconnected or with ultra heavy springs the engine will only draw what it needs. Sure this set up isnt for a stock 161 Holden engine but with the right engine combo it can be tuned and give you a wild looking intake set up.
