Being a newbie to using this style of caburetor, I am wondering what the differences are (if any) between the 8RT carb and the 7RT carb used by Ford? Thanks.
There is no functional difference between the two, merely year of application. This has been discussed on an earlier thread. See http://www.jalopyjournal.com/forum/threads/holley-94-7rt-vs-8rt.286727/
