hello there
so i have a 1966 mustang that i have been working on for few years now . The engine and transmission are on and everything seems solid. I need engine management that is kinda plug and play .

as far as i know that the holley kit was designed for the later 99 to 2004 cobra which use cop style. so is there anything else that is required other than getting 99 to 2004 valve covers , and new msd coil on plugs ? what about the sensors ? and what is the best kit i could get in my case !! . I search the
