The 289 engines are a little different from the Pick-Up (newer issues) and Panel van kits. The Panel van (all issues including the latest Harley Davidson release)has a Tri-Carb setup and side pipes, while the Pick-up used the same parts until the 1993 and later issues, which uses a "5.0" EFI setup with a normal dual exhaust setup, new tires and wheels, and etc. (they also have some of the left-over tri-carb parts in 'em too!).
Hope this helps,
