COX and COB cars finished in the UK have many differences small and large with CSX ones finished in the USA even if the chassis were built in the same time frame. Early CSX cars had all kinds of variations because more than one location on different sides of the country did the final assembly; every crew did things a little differently. As for COX6057, there is no mention in the SAAC Registry about it being fitted with any special engine equipment when first completed so I would wonder when the current induction system was installed and by whom. The Registry indicates the car had a Holley® carburetor in 1975 but no mention of how it got there. (Very few new Cobras, nine I believe, were documented to have been finished and delivered as new cars with any design or model of Holley carburetor.)


The majority of Cobras were finished in Venice California and most of them had hot air operated automatic chokes; 4100 series Autolite® 1-4V or two Carter® 4Vs. A few early cars received Holley carburetors with hot air operated automatic chokes; one was featured in a new car road test. Of the late cars finished with some type manual choke 1-4V only three Cobras were documented as being completed with high rise intake and Holley carburetor and those were CSX2497, CSX2553, and CSX2555. These cars were finished with GT350 intakes and manual choke carburetors, again based on what SAAC has documented. Of the cars finished after August 1964 that received ‘factory installed’ manual chokes there were two primary locations for the choke knob on the dash that I have found, one left of the steering wheel and one right of the steering wheel and other instruments. The exact location for each category seems to have depended on who put the hole in the dash, i.e. based on new car photos it doesn’t appear the assembly team used a template to locate the mounting holes but rather general guidelines.
