What is this Barracuda?

I bought my '69 Barracuda all apart. I mean literally in a hundred pieces. Minus the title and fender tag. The original vin on dash is present and matches the numbers stamped on the core support. I do know it is a real big block four-speed car. That is all I know. The body had been stripped of paint and any decals. I have some of the original build sheet, but I don't know what to look for. I am hoping it is a 'Cuda and not a Formula S. It did come with a factory tach in the dash. Can anyone help me identify this thing? Thanks!
