From that info all I can say is that it's either a 1967 350cc or 500cc unit twin model .

thanks so much.Yea you are correct. it is a twin 500.found the old paper work from where the motor was gone through in the mid 70's. it looks like they beefed up everything from pistons to cams.thanks for the help.
