Default GT Carb ??

I have a cobra jet Holley with both Ford and Holley nos. How can I tell if it is a GT factory carb. Thanks

When it was unbolted from the car, was the car a GT?

Factory Ford Holley (Supplied direct to Ford and made to Fords engineering specs) carbs have a 3 character date code and Holley aftermarket have 4 characters.

It might pay to post a pic of the choke horn and someone might be able help......I don't recognise the list number you posted and the cnaf prefix number doesn't ring a bell either, ie if it were a Ford Holley the second character would be a digit to represent the year of manufacture, the third the 'a' would mean full size body as in a Ford Galaxie for example.

Cheers Mick
