Early 260 powered 4V cars had Holley made Ford application carburetors that appear to be Thunderbird issue models. Don't know which one as all the several models looked the same on the outside. Soon a later model Holley made Ford application "square bowl" carburetor was used and was optional for 289 powered cars with the low rise aluminum 4V intake all the way into CSX24XX cars. Here's the last known version of low rise 4V (like most things Cobra there were several versions of intake and carburetor).
Only a small number of cars are documented with low rise aluminum intakes and Holley/Ford carburetors.
Most Cobras with 289 power and 4V induction got the same HP289 model Autolite 4100s are HP289 Fairlanes received. Three different models were used on Fairlanes between 1963 and 1965 model years so Cobras changed with them. Only two late Cobras finished in 1965 received the high rise intake and carburetor for GT350s, plus one Stage 1 competition car, plus one works racer for s brief period....four total.
