Hi Steve, If that is a 67 model its one of the more sought after(non-x/flow).Seems odd to have the tandem master cyl for brakes,USspec or retro fit maybe? Used to run one with 302 Boss/toploader/9" in circuit racing over here 30yrs ago. Can give you a list of parts and info reqd to make around 1850/1925cc if your game. Regards Jack.
