Bruce Sass,
I would assume this is who built the motor. Bruce is known for building excellent running motors and hes here in the Colorado area. Hes retired but does still do some motor work. When I spoke to him last it sounded like retirement is treating him very well. If you need contact info we can help.
Interested to see the bike. Can you post pics?

100% a bruce sass job, he built some wicked engines, he retired a few years ago. He still comes to the shop and is loving building his bikes and going racing
