i have a two barrel carb from a 68 fairlane off of a 289. it is rated at 287 cfm. i am not sure which carb adapter to use. ive read mixed feelings about both. has anyone used both? obviously i want to go with the cheaper and easiest install. but do any mods have to be made for either. i want to purchase the stovebolt carb adapter. how do you feel? also what is involved in the changing of the throttle linkage. any help would be great
