A convertible would run C @ 3285, D @ 3350, E @ 3520 or F @ 3685. These weight are class minimums. The convertible can't get to the top of C and would have to run 100 heavy for the class.

It's a GT build. A 68 Mustang coupe using the engine specs of the 302/230 found in the 68 Cougar. The rules say to use the heaviest gas engine body as the shipping weight, which is the 68 convertible 428/335 . That's where the 3369 comes from. The engine is rated at 220 with 10 added for the AFR 1399 heads.
As I understand it, GT is like building a car that never came off the production line even though it has the right brand parts in it. So a weight is assigned to the body and the class is determined by the engine factor. It could have been the actual weight of the body used (68 Mustang coupe) or an average 68 Mustang weight, but someone decided on using the heaviest one available. I guess.
