Sounds fishy. Other than thier exhaust Vance and Hines made very little of thier own parts, and to have them build an engine wasn't on the cheap.
I paid about $1000, 22 years ago just to have a head ported.
from the top of my head, The list was like:
Blocks for Suz and Kaw
Exhaust
Electrical items
The rest was they were distributors for Barnett, Web Cams, Weisco, APE etc...
