So, I was wondering, and I figured I'd ask on here first. What is an unrestored but free Whizzer engine worth, like how much would it take to buy one. I know that there's a lot of different models so if you could enlighten me I would really appreciate it. We have a 1950 Schwinn Panther that my Dad and I thought we would put a Whizzer on. Just tell me what you think! Thanks!
